Title: List your test equipment "scores" here!
Post by: xwarp on April 21, 2014, 12:07:35 pm
(I don't recall seeing a thread in the past 156 pages of threads where "scores" were the topic of discussion, so on with the topic!)

We are all always looking for bargains, so what was your cheapest score?

Mine, and I have several:

Tek 2246A scope with 4 10x probes with manual in great shape for $80.
HP 8013B pulse generator missing fuse cap for $3.
HP 3311A Function Generator $5.

ETA:

Tek 485 scope for $50.
For the automotive types, a near mint Heath Kit CI-1080 Exhaust Analyzer for $5.
A Fluke 10 DVM for $5 that I later modded to use the hidden Capacitance and Min/Max features.

That is all I can think of at the moment.

How about you?

Power Designs 1570 - 3kV 120W linear power supply for $30

Hmm...
a Tektronix TDS-380 for $140, not quite a steal, but a decent bargain for 400 MHz, 2 GSa/s...

Numerous old Fluke bench DMMs in the $5-15 range needing small repairs

Can't think of anything else particularly good at the moment.

My best deal to date is a set of 8 standard resistors and 5 standard capacitors for $50.  The caps are worth several times that individually.  There have been other good deals, but none as good as that one.

How did you all get such good deals? Garage sales? Dumpster diving? Donations?

I don't have much test equipment to begin with, but I did receive a free >200 mW green laser from Wicked Lasers in exchange for a review several years ago. That particular model was sold for around $1,000 at the time. :)

Place I contracted for a couple of years. They closed down a year or more after I left, the local 'equipment companies' offered $0 and not to charge recycling fees - so I got 1st dibs on anything I wanted... The phrase kid at a candy store was close to how I felt that day.

cheers,

Not sure if this counts as a "score" seeing all others incredible deals, but this one just arrived today:
(http://i.imgur.com/j4LOn6p.jpg) (http://imgur.com/j4LOn6p)

It's a Korean made 100kHz-220MHz signal generator. Got it for about $100 shipped to my door. Not in the best of cosmetic shapes but seems to function correctly. No idea about its accuracy but I'm not bothered. It's the only equipment I have now that can generate frequency higher than 25MHz. I hope it will help me run some basic tests to judge quality when I start doing sourcing of things like BNC cables, etc.

Hi Frankie, there is something about the look of that Freq gen that reminds me of some older vintage HP gear I have esp the modulation type leds, its not an old HP rebadge is it?

It says "Made in Korea" at the back so I doubt it's an HP rebadge. Older HP equipment were mostly (if not all) made in the USA, weren't they?

My best score was a practically as-new recently calibrated Audio Precision 2700 for $500
http://www.ap.com/products/2700 (http://www.ap.com/products/2700)
Sold on ebay for $14K  ;D
Wasn't supposed to get it, but was in the right place at the right time with cash.

From the same score I got other bargain like a portable TDR still in cal for $20, sold for $1500 or so I think on ebay.
An Agilent 54622D (not the one recently) for $100 and resold on ebay for $2200 or so.

Not electronic test equipment, but I scored a Nikon S-Ke and Wild M40 microscope plus a bunch of accessories for around US$45 a week ago   :-+  (ebay indicates a value of at least US$1000)

Sadly, still trying to figure them out  :palm:

A few months back, I picked up a Philips PM3209 (with original probes and manual) plus a Escort EGC-2230 function gen (fixed it with $6 replacement chip from ebay), also around US$45.

Also, bought a Tek TDS340 (with a single original probe) for US$270 (oops brain fart, not 135), but it was a dud (faulty memory I think), but managed to resurrect it with a TDS360 mainboard I managed to get for US$90 from ebay (200MHz now!!)  :clap:

From the same hamfest-Tek 2235 for $40 and a Fluke 1952A for $10, both working,.  The price for the FLuke was $15 but there was 2 of them, myself and another ham were interested in both so the wife of the seller said $20 for both.  The husband didn't argue with his wife on the price and neither did we :-DD  You have to love SWMBO, even when she isn't yours.

Not test equipment, but was at my mates car lot years ago when another trader turned up looking to sell a Suburu WEX, except he didn't realize it was a WRX. I quickly paid him £2500 for a £6000 car and had just finished sorting the paperwork before anyone else realized what a bargain I'd bought.

Brymen BM857 for ~$78 shipped, new
Agilent U1252B for $300 (due to a rebate, new)
Power Designs TP343B ~$90 shipped

The rest of my T&M gear wasn't horribly priced, but not huge scores by any stretch of the imagination, such as a Tek2445B for $280 shipped.

Non T&M would be a Weller WD1001 ~$240 new for example, getting new Tronex cutters or other name brands for $20 per or less, barely used Ideal-Tek tweezers for ~$8 per types of things. Most recent would be a 2 layer rubber ESD mat on clearance from All-Spec (~$22 for a 30"x60" size before shipping and the rest of my order).

About 10 years ago I scored a really cool HP 8601A sweep signal generator for about $80. Really cool unit dating from the I think late 60s. I did a tare down and the internal construction is very impressive. The output attenuator assembly is very accurate and the unit still functions great. It was designed for servicing of TV, FM and AM radios.

I bought a Tektronix 2225 in perfect condition with a lab cart for $100. The cool thing is that the cart had a drawer that was full of cables, probes and adapters. I think there were about 10 Tektronix oscilloscope probes in that drawer as well as a logic probe, a temperature probe, and some other things I still haven't figured out.

55" Samsung 1080p LCD TV with a bad power board for free.
Cost me $90 to get a new power supply board, but it's going on the wall as an output for the Owon o'scope and the microscope!

The best deal I did so far was a 87-V, about US$ 180~200 (but here a new one is about US$ 1200,00). Looking perfect, with the tests leads. It only likes a good deal here, but it is for me.
And a agilent E3649A power supply, new unit, by about US$ 300,00. Local prices for a new one is about US$ 2500,00. I still don't know why, but they told me by this value, and I bought. :)

best score.


tek 2445 (150Mhz)  for £100. needed re caping on the main filter caps.

tek 2467b (400mhz)  for £170. changing a stupid resistor made the scope work again.

I generally look for broken equipment and fix it, so most of my lab equipment cost less than $100.

Let's see
  HP 3456a $50 - working
  HP  4262a LCR meter $100 - needed a button cap
  HP 5004a Signature analyzer - $20 - needed a filter cap
  HP 3325a function generator - $50 for 2 nonworking units - still working on this one, it's about 90% working now
  HP 6236b triple output power supply - $50 - needed 2 filter caps
  HP 16534 2Ghz 2 channel DSO scope plugin $80 - needed a selfcal
  HP 16533 1GHz 2 channel DSO scope plugin $20 - new, in box
  Tek 465 with cart and probes - $50, needed filter caps
  3 Tek 7603 scopes with various plugins - free
  Tek 2432a DSO - $50, had a shorted tant and needed a couple diodes
  Tek 422 - $35; it's a cute antique, I keep it out in the shop with the CNC stuff.
 
I prefer free, but $50 is a good price point.

There's other stuff, but those were the best deals.

There is a local liquidator that I sometimes visit to see if they have "broken" equipment.

I've picked up some good stuff for cheap.

And of the scopes that I have:

2 ea. Type 422's, one ac p.s. and the other is an ac/dc - battery pack,
1 VU Data PS-935,
1 Tek 2246a

I use the 422 the most for what I mess with at home.

From an US liquidator, including taxes and customs duties:

needed repair of power switch, replacement of a burnt 2W resistor for the current source, and cleaning.

HP5335A, opt. 010, 030, 040: universal counter 200MHz / 1ns, OCXO, extended GPIB capabilities, C-input 1.3GHz , 330€

I got a fluke 87v on eBay for £160 I bided on it with 3 seconds to go  :-+

I got one of those for £123 with 3 seconds to go :-+

A nice mint one too. Auction ended in the middle of a weekday afternoon.

About a month after that one, an 87V E2 Combi kit appeared - brand new and complete (the kit comes with a nice C35 case, the Tpak hanger, and modular test leads). It was just £150 BIN! I sat on my hands for a good half-hour, hoping someone else would snap it up, but in the end I couldn't help myself  :-DMM

I was pretty pleased with a mint Fluke 45 for £78. Sometimes on eBay you get lucky. Other times, you walk away...

That said, most of my stuff has been free. Normally needs repairing, of course, but that's half the fun. It would be vulgar to list it all, but rest assured that it's all used and cared for here...

I found a Keithley 199 in good looking condition listed on ebay as not working. The display showed only "------". I happened to have one 199 already, so I knew a thing or two about how they work, and I had a hunch that it might be user error. When it arrived, I tested it and sure enough it displayed "------", so I pushed the trigger button, and it started taking measurements perfectly. :-DMM I paid $20.

Almost exactly the same situation a year later with a Keithley 2001, 7.5 digit bench meter. Displayed only "------" and was listed as not working. I scored that for a really nice price with make-an-offer. Again, I "fixed" it by pressing the trigger button.  :-DMM It has a fault measuring ACI but all other measurements are spot on.

So, sometimes when they say "It doesn't seem to work and I don't know how to test it" they are telling the truth. But not always.

I once picked up an HP 1741 100MHz dual channel scope, including the accessory pouch, cover, manuals and probes for $25.  I was at an automotive swap meet (Raceway Park, Englishtown, NJ).  It was sitting under a guy's table.  I asked him about it, he said it was his son's and was taking up space in his garage, so he brought it to get rid of it.  He was asking $50, and I talked him down to $25.  When I got it home, I cleaned it up and checked it out.  All functions worked perfectly, and it had a nice clean trace.  I brought it into the cal lab at work, and everything was still in spec.  I later sold it for $300.

Fluke 27 II, meter only but brand new / unused milsurp with fresh cal and plastic still on the screen, $90.
Tek 2465A, with probes, adapters, front cover, all the extra bits... had a bent handle... $105 shipped to my door. Fixed the handle, works like new.

I don't ever get test equipment for free... I get TVs, AVRs, speakers and other stuff like that though, old or new, good or bad...

I got an HP frequency counter cheap that way once.  Seller showed it powered up but said it was broken due to a displayed "No Osc" error message. And of course, the rear panel photo showed the switch set for an external timebase. :)

Deals like that help balance out the times you take a gamble on an "as-is, no return" item, and find it has been cannibalized for internal parts...

mostly on ebay but some from local surplus stores.

notable good deals I got:

keithley 2015thd for $400
tek 2465b for $400
power designs 5020, 2020, 2005 psus: $50 to $100
metcal mx500 station: $150
pace mbt desoldering (with every spare part imaginable): $350
hakko hot air 850: $120
hakko hot tweezers 950: $50

agilent function generators, power supplies, fluke 45 (2 of them), misc other lab flukes all at 'motivated' prices over the last few years.

very few things just given to me, but frequent searching of the bay and local surplus stores have helped build my home lab to where its competitive with many small and even medium sized bay area companies.

I have so many duplicated boxes (function wise) I am running out of room and should sell the ones I don't use anymore.  I like buying on ebay but afraid to sell there: too many scary stories and I just cannot afford to be ripped off by buyers who are less than honest.  maybe I will try to craigslist my extras.  too bad ebay is just not worth selling on, anymore (for me, anyway).

What's the problem with ebay? You would accept PayPal only, right?
I thought that was safe, on both sides (although I only have experience as a buyer).

Please enlighten me :)

sceanario: sell a piece of good gear on ebay.  buyer gets it, swaps it with a broken unit (or breaks it himself) and returns it.  even worse, he could return a box of rocks and as long as it has the right weight and was mailed to the 'right' address, paypal will not side with you.

just too much risk.  if there was a trustable escrow, that would be great, but I have not heard of that for years.  I did use an escrow once when I was buying a $1k used camera body, but that was nearly 10 yrs ago.

buyers have more rights than sellers and you have to hope you don't run into a bad buyer.  most buyers are probably fine and most sellers are, too; but the risk is just too high for several hundred dollars of gear, each.

also, paypal can freeze your account and hold your money for as long as they want (in the US).  they are NOT a bank and can get away with murder.  if I'm buying, I don't have funds in my paypal account, but if I'm selling, I would; and I simply do NOT trust paypal to 'watch over' my funds.

when ebay was a garage sale style site, that was great.  now its mostly about power sellers and cheap trinkets.  the nice multi hundred dollar test gear is not what ebay is about these days; they are about selling cheap junk from china and the small time seller gets no respect from paypal or ebay.

I can't average out my losses and so if even one of my meters or supplies gets stolen by a bad buyer, it would crush me.  I'd rather keep the gear and not make money from it than risk being an ebay seller, to be honest.

You guys are making me drool here. I found a Kinsten UV light box along with a large supply of etchant, drills, photosensitive board, transparent film and misc other stuff on Kijiji once for pretty cheap. Can't remember how much but I drove quite a few miles for it. I've had tons of use out of the light box and am still working on the chemicals. I never seem to come across used gear.

Yes I agree with echen1024, most people are honest.
But I see linux-works's points too, and if he doesn't want to take the risks then that's ok.

All I can say is that I have bought a lot of stuff from ebay (from all kinds of sellers ;D) and have never been stinged. I would have expected it to happen a long time ago.

Good idea IMHO, and only use PayPal for payment.

Should reduce risk exposure, and still keep monetary aspects easy enough for both parties, as well as reduce the fees for linux-works.

before ebay, back when USENET was a good way to buy/sell gear, I used to use COD a lot.  you could check 'cash only' on the form and not have to worry about getting a bad check.  easier: have the receiver go to the PO, buy a money order right there and that is what gets sent back to the seller via return mail. COD also ensures the mailman can't just leave the box 'in the bushes' since he has to collect money from the buyer.  it also motivates the shipping company to treat the box a bit better, as the receiver won't even sign for a box that is beat up.  it helps everyone on both sides.

no one seems to do COD anymore, though.
Title: Re: List your test equipment "scores" here!
Post by: N2IXK on April 26, 2014, 09:07:08 am
No, COD went away because neither private delivery companies nor the USPS want to go through the expense/hassle/accountability of having their employees bonded for handling cash.
Title: Re: List your test equipment "scores" here!
Post by: linux-works on April 26, 2014, 09:11:01 am
you can still ship COD via USPS.  did they fully take that option away?  I know its not commonly used but I didn't think they removed the option.

not sure if ups/fedex ever took COD.

also, one good thing about using US mail (for those in the US) - is that if there is misrepresentation, its mail fraud and that's taken pretty seriously by the post office.  used to be, at any rate.

even if you only do the COD for a token $10, it ensures that the postman HAS to meet a real adult person and not some random person who will 'accept' the box or the postman just leaving it 'with a neighbor'.  the end-to-end reliability of COD was really a neat thing and worth the cost to me, for sure.

Well today, I picked up a "box-o-meters".

Happened to see the ad at the right time to be the 1st caller on it.

Key pieces are:

Fluke 52 thermometer
Fluke 83 series 1 in good shape
Fluke 87 series 1 in good shape
Fluke AC current clamp
Fluke 27 in ok shape
Some probes and what not.

oh.......

A Fluke 189, works, but the battery terminals are damaged from leaking batteries.

All for 2 Benjamins

You can also get good deals buying ex rental RF test gear that has reached the end of its 'rental' life. eg stuff that is no longer supported by the manufacturer for spares or repairs. When this happens the rental company will often offload the equipment cheaply.

I've bought some seriously good test gear this way numerous times with some fantastic deals although you are usually looking at fairly expensive lab grade test gear. But you can sometimes get ex rental items at about a third of the price of the typical ebay 'buy it now' price from the various online test gear dealers. You can sometimes buy stuff that is still officially in calibration. eg I recently purchased an HP/Agilent sig gen that still has most of its 2 year calibration left on it. i.e. the Trescal calibration sticker expiry date is in 2016.

Note: there are obviously advantages and disadvantages to buying ex rental gear. But the biggest advantage is that you know (within reason) that the gear has been properly maintained/serviced and calibrated over all of its life. Also, rental companies tends to fit the top options to the test gear to improve the appeal of renting it. The sig gen I bought had two very expensive options fitted and a VNA I bought from the same company had every single internal and external option with it. So you kind of get these options for free.

I picked up a perfectly functional MFJ-259 antenna analyzer at a ham radio yard sale for $10 with the case.  Both of the 9V battery connectors were bad so I replaced them though I haven't gotten around to buying the battery holders yet.  I use it with a wall wart that I had so the holders aren't a big deal.  It has more than paid for itself for my own antennas and for helping other hams with antenna projects.

I had to replace the battery holders on an MFJ-259B and luckily MFJ sells replacements. Mine were melted through at the AA battery terminals so I wonder if the user tried to recharge normal batteries.

As for my best test equipment scores

Fluke 9000 microprocessor tester (working) $20
Fluke 9000 Z80 pod (working) $10
2x HP microwave attenuators (working) $20
Meguro THD analyzer $20
Fluke PM3082 digital scope with a broken power switch and missing knobs but working $20

Off lease gear sometimes gets dumped at hamfests especially if it has problems and isn't worth it for them to repair. I have a pile of Tek 24xx and TDS 7xx series scopes that I need to recap or fix random issues (GPIB errors, bad focus, etc). The caps on the TDS scopes are going to be fun.

$20 at the local swap meet last night. The meter appears, in comparison to my Fluke 189 is pretty darn close in readings.

The last calibration done by Fluke on it was Sep of '86.

I've just bought a HP85644A tracking generator source for my HP8566B spectrum analyser.

These cost about $20k when new in the 1990s and are quite rare. I got this one for about £175 +PP on ebay as a non runner  :)

It was advertised as 'won't power up' but all that was wrong was a blown fuse due to someone running it at the wrong input voltage selection.
It's now running fine. See below for it running in cw mode set to a frequency of 5GHz. In the other mode it runs as an external tracking generator for the analyser :)

Rebadged LEM Analyst 3QC power quality analyser, appeared to have never even been used. Due to the woefully inadequate item description, plus the daft auction end time (very few eBay snipers around at 4am) I think it set me back £230 inc. postage. Add a zero on the end and you get the usual price for one  ;D

Datasheet here (http://www.farnell.com/datasheets/56128.pdf)

No longer available, the closest match being the Fluke 1735. Same case (but in Fluke Yellow instead of LEM Blue), same probes, same screen, less functions, £2,700.

The HP 8640B in the pic was free. When found it had been out in the weather for some time, sitting front face up. It had been rained on, and I grabbed it assuming it was probably ruined, but still worth a look.
Amazingly, due to all the guts being in sealed modules, there was virtually no damage. Cleaned up some water drip lines and stains inside, and it ran. The painted numbers had peeled off the back of that clear dial on the AM modulation frequency, and it took years to find a replacement. The frequency meter module had a logic fault, which may have been why it was tossed originally. An easy fix.

But this kind of luck is pretty rare for me. Usually I see nice gear being sent to destruction by corporate pointy-headed boss types, and don't have any opportunity to save it. Or hit the PHB types with a flamethrower, which is what I'd like to do.
A whole warehouse full of such stuff once. Sob.

HP 4815a Vector Impedance meter with probe, manual and a spare 4815a for 120$ total.  The first had a minor power issue that I fixed and works perfectly.  About a year ago I picked up the cardboard impedance calculator for free and didn't know what it was for until I saw the picture of a 4815 on it.  It is referenced in the manual as well.

Agilent u1252b with two sets of probes, the high end probes, calibration, charger, thermocouple, and the thermocouple calibrator, all brand new for $240.  That is one hell of a meter.

Tek tds3054b for $1200 as new.  I don't think the guy who sold it knew what he had.  He was selling it for his brother who was in China.  Would be interesting to know what his brother says when he gets back.

My personal fav, my TDS 744a with six probes, case, terminators, etc for $400.  I recently upgraded it to a 784a and it is near perfect as well.

All of that stuff was just getting really lucky on ebay. 

The PCIe protocol analyzers are very specialized pieces of equipment.  It's not like a DSO or an SA that you can use for all sorts of stuff.  A PCIe analyzer connects to a device either with some sort of flying lead probe or with an interposer card.  It captures the data on all lanes of the bus in both directions and stores it, then decodes all of the transactions.  I have been doing some work with FPGAs and PCI express and I did a quick ebay search to see if there was anything available.  As luck would have it, there were actually two different systems available - one 8 lane, and one 16 lane, both with interposer cards.  I actually bought both of them, one for myself and one for the lab.  The analyzers are specialized equipment, so the list price is high and the resale value is low, and they depreciate like mad.  Agilent also makes gen 3 capable analyzers now so they're a generation older.  The 16 channel analyzer is two cards at $30k each, plus $20k each for the 16 lane licenses, plus the cabling and interposer card, IIRC.  Most people who need one are manufacturers doing PCIe compliance tests, and they would just buy it new from Agilent.  It's actually a rather significant PITA to use - the dang thing is network booted and requires a dedicated network card, and the software package installs about 5 or 6 services (FTP, DHCP, etc.).  So I have to run it in a VM and then use a USB network card, and everything has to be turned on in the right order.  And usually it doesn't come up on the first try and needs to be power cycled.  And then the software is rather unstable and has a propensity for crashing.  But I did manage to find two different bugs in the Altera PCIe reference design with it.  The actual capturing of the PCIe bus is performed with a Virtex 4 FPGA and several GB of DRAM.  The analyzer cards and interposer cards actually have a rather interesting stackup - the inner layers are all standard FR4, but the top and bottom layers are some sort of RF substrate - rogers, duroid, or teflon - so the boards are very bright green with white bands around the edges. 

The differential probe was just luck.  I have had a watch on infiniimax for months, and it popped up along with a differential SMA adapter.  The thing had a nasty gash in the outer insulation on the probe cable and it was sold as 'untested'.  I figured it would be a good deal if it worked, so I went ahead and placed a reasonable bid.  Turns out the gash only affected the outer insulation, the coax and low frequency wiring inside were all fine, so I just taped it up.  It works perfectly with my Infiniium 54854 4 GHz DSO.  I have not tested it with the DSA91304A that we have in the lab yet.  Oh, I also managed to score a set of 4 new in sealed original packaging Agilent custom "BNC" to APC 3.5 mm precision adapters and an infiniium calibration cable for like $150.  I paid $10 for the cable, which was mislabled so nobody found it.  I only found it because I was browsing the other items of the seller with the adapters. 

The tracking source is an interesting story; originally it sold as 'untested, as-is', but listed as 'used' for $3500.  And it was a suggested item for something else I was looking at - I didn't even know such a beast existed before I saw it.  However, the guy who bought it is a bit of an a$$hole who buys instruments listed as 'used', testes them and gets them calibrated, then sells them for 2x (or more) what he paid or returns them if they don't work, even if the original seller listed them 'as-is'.  (if you list anything on ebay that you don't want coming back to you because you didn't test it and it turns out that it does not work completely, 100%, you cannot list it as 'used' on ebay, otherwise some dude will buy it and return it and force you to eat the shipping cost due to the implicit ebay guarantee on used items)  So two or three months later, it turns up again, listed as 'parts or not working' for $2k.  I contact the seller and ask him to run the self test.  It comes back with an ADC vref error.  Hmm, sounds like a bad power supply.  I manage to talk him in to parting with it for $1k.  After I get it, sure enough, +32.5v is reading zip.  So I pop over to radioschmuck for an LM317 and replace it, and remove the shorted capacitor that caused the failure.  A few weeks later it stopped working again.  I traced that one to a failed 1 M ohm resistor in the power supply power good detect circuitry.  Again, a trip to radioschmuck for some 1 M ohm resistors later, and it's operational again. 

As for the OE converter...I bought a 83440C from a guy on ebay for around $200.  A few days later he lists an '83440C' with no label, but it has an adapter of some sort attached to the RF side.  Looks like an attenuator or something.  However, the actual connector on the device is a different color.  The 83440C has a 3.5 mm connector that's good to 26.5 GHz.  The 83440D has a 2.4 mm connector that is good to 50 GHz.  3.5mm and 2.4mm are not compatible with each other, they have different threads and different center pin sizes.  (FYI, SMA, 3.5mm, and 2.92mm (K) all work together, and 2.4mm and 1.85mm (V) also work together)  To highlight this, the 3.5mm connector is gold plated while the 2.4mm connector is silver plated (probably nickel, but I'm not entirely sure).  Anyway the connector on the '83440C' is silver, just like all of the 83440D.  So I made the guy an offer on it. 

I also picked up not one, not two, but THREE old ASIC emulators from ForteLink (now part of Synopsis, so no hope of getting any sort of documentation) that each have 11 large Virtex 4 FPGAs one one gigantic board. For around $2k for the lot. 

So, if you want screaming deals, you need to cast the widest net you can (general watches on ebay), be willing sit and wait for a long time, contact sellers and make offers (many of them don't know much about what they're selling), check out everything a seller has listed (you might find something really interesting), and be very observant.  Eventually, you will get lucky and get a really good deal on something.

Agilent DSO-X 3034A in mint condition (but no options enabled..)
+ a mix of 5pcs 500/600MHz 10x passive probes

$3200 including shipping / ebay. Not a huge 'score' but significantly cheaper than a refurbished one from  keysight ebay-store AFAIK.

should be enough of a scope for most hobby projects - luckily there is faster gear at work if needed ;)

I just bought 5 Vision Original Mantis (with x2 and x4 lenses) and 2 Vision Mantis Compac (with x4 lens). It was sold as part of shutting down a local seismic acquisition company. It will start up again in the Far East, Malaysia or something, to save costs.

I haven't received the lot yet, so I just hope the instruments are in good working order. I will probably keep one of them and sell the rest on eBay.

Small list of my "scores":

- Metrix MX9030, Differential Probe, 30 MHz. Bought for ~45€ + 15€ for spare parts.

- 5x Tektronix P5205, Differential Probe, 100 MHz. ~50€ for all five probes. Only the attenuation switches had contact problems. Fixed that and build my own Tektronix 1103 power supply.

- IV-CAL, voltage/current calibrator. Bought for ~40€ + 20€ for spare parts

- Siemens calibrator 03, voltage current calibrator, for 15€. Still needs to be repaired.

And a couple of extraordinary test equipment, like a Wandel & Goltermann SDH/PDH transmission and jitter analyzer. No use for it. But it was cheap and fairly interesting to take a look inside  ;D

Of course, it was all so cheap, because it was defective. But in the end good deals.

Oh, and apart from all that test equipment, I bought a digital photo frame from Sony for 1€ (new: 200€). Fixed the dead diode right after the dc jack and gave it to my mother. She was very happy  ^-^

That picture was causing some worries, but the seller assured me that everything was carefully placed in the bin. I made him individually bubble-wrap the instruments, before a friend of mine picked them up.

I wonder why anyone would present such delicate instruments in such a bad way.

I just got a HP 6050 Load mainframe for $575 US ($700 Aussie Dollars) Plus shipping. That price seems to be pretty standard, but this one had 5 x 150w load modules installed.

When I got my hands on the unit, everything is in great condition and working. Accurate to 15mA from what I can test and the last cal sticker was 1996.

Been doing some power supply tests on it since it arrived to see if there are any bugs or glitches, but nothing so far.

It wasn't as good a deal as some of the ones on here, but I am really happy with it.

Got a HP 141T (0-110MHz modules) and a HP 8640B in a barter for assembling some radio gear
Got the HP 10855A preamp for it, for $12

about 15 years ago, when I was big into weak signal VHF, I scored a NIB (OEM hard case) Polarad sig gen (800M-2G(~))with matching modulator, for $200

Fluke  332b $185.  Was marked for parts or not working.  Turned out it was 100% good, the voltage trip control was turned down.  OK, I did have to replace 2 incandescent indicators for the decimal points.  Extremely clean inside; even included the extender card.

Tek 7904 scope $25.  No plugins, I bought it for parts, was supposed to have a PS fault,, but turned out to be fine.

HP 5005b signature analyzer $12 in the buck a pound box at a hamfest.  100%

HP 54620a LA with cables, $55.  I got this because the cables work with my 54645D and the cables by themselves go for 150-200 when you can find them.  Turns out it's not a bad little LA.

I got an old HP 54502A 2 ch 400MHz scope from work. I knew it was busted. 1 channel was broken, it failed most selftests and the psu was failing (I used the previous one to repair my work scope, an HP 54503 or 54501 4ch 500MHz scope). Luckely it came with all original printed manuals, service manuals and a brandnew sealed input module. After placing it, replacing ALL psu caps and placing a new nvram all is working fine again.

Got lucky with a free Keithley 199 too. It couldn't be used no more because the new pc had no ISA slot for the GPIB card, so the meter couldn't be read  no more. All it took was a calibration on all but the voltage settings because the cal settings where lost. I really love this thing.

Got some other free stuff too. Most is BER, outdated (not always for me), or It would just take too much time to repair. A HP8116A took me ages to fix. The low freq stopped sometimes. After weeks I found it was the freq sweep input connector which was a little crusty and created a voltage divider with the pull-up. Just around the 1-2volt range on a ttl input |O

Despite my luck with two oscilloscopes, I think electronic gear is expensive and a little hard to find in the Netherlands too. A multimeter can easily be 50-100 euro's more expensive over here - compared to the prices on test equipment depot and testequipment.net.

This can only partly be explained by the high VAT (21%). Maybe they do a very 'safe' dollar/euro conversion, or maybe the market here is too small for good competition.

Yes, most gear is verry expensive in the Netherlands. I guess its because of the dollar. So obviously second hand prices are higher too. But every once in a while someone doesn't know what he or she is selling. Those are the good days  :-+

That's how I got my Tektronix 465B: I bought it from an university, they decided to get rid off old equipment, but they let the students do the actuall selling... The original price was 35 euro, but before I got it they were told by a professor to rise the price. It was still under 50 euro if I remember correct.

A couple of years ago on another forum, a guy decided he was getting out of the microcontroller and electronics hobby. He wanted to sell his entire collection of stuff for $250. After a few days, I offered $225 shipped and he accepted.

I ended up selling most of the stuff on eBay. I stopped once I had recovered my $225 investment. What I had left (among other minor items) was a Parallax Optascope 81M USB oscilloscope, which still works to this day, and a brand new, never used and still in the original box, Hakko FX-888 (the analog version).

Since I already had two soldering irons, including a Hakko 937, the FX-888 is still unused, just sitting on a shelf in its box.

When I received it I found that the auction listing wasn't accurate. They hadn't bothered to mention the box of 2 dozen probes that came with it.

Just those probes were worth my winning bid for the 7704.

Not sure how much of a score yet, but I got an HP E3615A DC 0-20 V, 0-3 A, 60 W Power Supply for $75 including shipping.

Unit powers on but no further tests was done and sold as is, it does have the back connector to link to other supplies but I only went for one.

Negative binding post is red??? and ground binding post is black???

At least the positive one is red :)
I'll swap the negative and ground and search for a green binding post to replace the red one or just paint it or something.

Look in pretty good condition (other than the binding posts with the wrong colors)

I think HP had a problem with the binding posts breaking on some of the E-series supplies. I got a 0-120v model for a song a few years ago and found that the negative post had cracked behind the panel. A little epoxy and it works like new. Maybe the former owner of your supply had some spare off-color posts laying around?

That's the way HP made them at first. Around the time they turned into Agilent there was a minor cosmetic refresh and one of the changes was switching to the red/black/green binding posts.

Not sure how much of a score yet, but I got an HP E3615A DC 0-20 V, 0-3 A, 60 W Power Supply for $75 including shipping.

Classic, I bought one of the others (there were three for sale).  I'll be interested to see if it works, but I'm not really worried, looking at the description they should be at least an easy repair.

I've got a couple of other HP supplies (6205C, 6237A), and they've got the same scheme, all red except for earth.  They seem to have changed to red / green / black only a little before becoming Agilent.

And that's why I didn't post anything about the auctions in here or I wouldn't have a chance in hell.

I did let go the first one, I could have outbid it easily but decided to get the first bidder out of the way plus one of the standoffs had the ring broken and they got it for $4 less of what I got for mine.
I got the 2nd one for $0.25 over the 2nd bidder :)
and the 2nd bidder on mine tried for the third one but someone (you probably) got it for just $1.00 over.

Unless you are the one that got the first one, but even with the post ring missing it shouldn't be a problem on that 1st one.

Snapped up an Advantest R6581 for $500 a while back, it's an 8.5digit multimeter. Think of it like a baby 3458A, 2-3 times worse on linearity (0.1ppm) and noise(0.025ppm RMS), but it does have artefact calibration and hey, I can't really complain because of the price. I dig the dual line display, it's very easy to use. 5ppm per year accuracy on DC volts, and a tempco of 0.15ppm with autocal.  :-+

The seller described it as broken, because on power-up there was no reading shown, and the relays were clicking non-stop rapidly, hence listing it for so cheap. This meter always self tests on power on, and the seller's photo did not show any error annunciators.

Upon arrival, yep, it's as the seller described. I ran the internal calibration (which is like the AutoCal on HP), and hey, it all seems to work just fine until I power cycled the meter. It then showed error -315 "configuration memory lost".

10 bucks and 2 solder joints later, she works a treat. It's a standard 1/2AA 3.6V battery, axial lead with 1.25inch spacing. Access to the battery is easy, just remove a couple of cables in the way, there's no need to take off any shielding.

The local cal lab said it was 9ppm off on 10V DC, and was adjusted to be 0.3ppm off. There weren't any stickers on the unit I have so who knows when it was last calibrated. I don't have the cash for a proper calibration with a Josephson-Junction ($1.8k+), so I'll have to live with their stated 2.4ppm uncertainty. They did have their 10V reference freshly calibrated, hopefully it's a bit better than that in practice.

My unit was made in Feb 1998 according to the battery, and there must be other units running out of batteries, so I hope by posting this you guys can snag a good deal too!  ^-^

Hi Deadly Lover,

as a 3458A / AUTOCAL owner, I'm greatly interested in a teardown of the mysterious R6581, and maybe you have any manuals to share. (these are not available on the net)
Especially I'm interested, how the autocal and in conjunction the basic calibration of the R6581 works,  i.e. if also 2 artefacts  (10V, 10kOhm) are necessary only.

Yup, it is also 2 source 10V and 10kOhm artefact calibration, same as 3458A.

It has something called "Internal Calibration", I suspect that it is just their version of AutoCal as the spec sheets indicate that it's for the tempco compensation. You can perform the INT CAL separately for DCV, Ohms and AC, just like AutoCal.

I'm also curious how it can calibrate ACV, ACI and frequency ranges, maybe you simply cannot? I couldn't find anything about it in the manual. I guess because it doesn't have the fancy synchronous AC mode like the 3458A, there is no need for adjustment for the R6581 AC ranges. It's ACV specs are nothing to write home about, pretty similar to the 3458A in analog AC mode. It is quite a mystery...it lacks an equivalent of SCAL on the 3458A...

There are no English manuals unfortunately, the only one I can find is in Japanese on the ADCMT site and is a pain to translate because Adobe Reader has a hard time recognising the Japanese characters. The pages were scanned as images.  :-\ I uploaded it here, it's a biggie at 35MB. https://www.dropbox.com/s/67vd6qj0ob7mh5h/R6581%20manual.pdf?dl=0 (https://www.dropbox.com/s/67vd6qj0ob7mh5h/R6581%20manual.pdf?dl=0)

You can find some good teardown photos of the R6581T here at 38hot, it may be slow to load because it only loads pictures as you scroll down. http://bbs.38hot.net/thread-212-1-1.html (http://bbs.38hot.net/thread-212-1-1.html)

The difference between the R6581 and the R6581T/D is that the latter only has DC and Ohms functionality, and with limited range on DC, like 100V DC range maximum.

I really don't want risk messing with the R6581 calibration until I acquire a stable voltage and resistance reference, so I don't think I can teardown the unit just yet, sorry! It will happen eventually though, I'm sure!  :-+

I was very impolite.. sorry..

"Congratulations on that great instrument!!"

The bbs38hot site, lyemx himself, answered many of my questions, and even the Japanese manual (Geez, 680 pages w/o schematics) also revealed enough information about the specs.
No need to make a further teardown.

Well, they also made a much better use of the LTZ1000 (non A) reference, at 65°C only, compared to the 3458A.. and intensive use of bulk metal foil resistors, like in the Fluke 8508A.
 These BMF resistors are from Alpha Electronics, which I already used in my  reference divider (752A clone) .. Good stuff...

If it even turns out, that the AUTOCAL feature works nearly as good as in the 3458A (doubt that a bit, 'cause of the worse linearity), then this could be the Swiss Army Knife of DMMs


Thanks again for sharing

Frank

P.S.: the strange A/D converter hybrid in the R6581 directly reminded me of the PREMA 26bit converter:
http://www.ohh.de/5610.htm (http://www.ohh.de/5610.htm)

PREMA also made an 8 1/2 digit DMM, based on their A/D technology, but I dunno which A/D they used inside.

One of my best scores, from about ten years ago.
The Wayne-Kerr B221 admittance bridge measures capacitance in parallel with conductance at 1591 Hz (10,000 rad/sec).
The bridge is based on ratio transformers.  So long as the number of turns does not change (integers are the only exact things in life), the accuracy depends on the internal standards, which are hermetically sealed.  Front-panel switching allows measurement of negative capacitance (inductance) as well as negative conductance, using the transformers.
Checking against lab standard capacitors, no tweaking of the calibration was required (roughly 50 years after manufacture).  The only repair required was replacing the line cord, which had been somewhat butchered by the previous owner when switching from UK-style to NEMA plug.  I have purchased replacement vacuum tubes, but have not needed to replace any yet.
The best thing about this unit is the bridge null indicator:  two cascaded dual magic-eye tubes.  They "close" in sequence as the signal approaches zero, with no meter lag.

So my HP E3615A DC 0-20 V, 0-3 A, 60 W Power Supply arrived today and I powered it up since the auction showed that it powers on.

Constant current works from 0 A to what I want to say Pi (3.14 A)
Voltage goes up to 21.6 V and I did set the OV to 24.5V

Tested the over voltage by setting it to just 12V and it works.
Tested the CC and it works fine as well.

Grounded the negative post so I could hook the PS to my scope.

It does has a 5 Vpp short pulse at power up, then it has another shorter one when the power supply finally engages 60 ms later (a bit longer for the upper voltage range) these transients are very short lived, and the supply reaches the voltage around 50 ms later.

Here is the power up with the supply set to 20 V, the first arrow is when I throw in the switch, the 2nd is when the supply starts supplying.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=142670;image)

The problem is that at lower voltages they are still there, here is the power up at 10 V, on power on it still has the 5 Vpp
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=142672;image)

At 3 V, it's almost overshooting when it actually starts, but the power on goes up to 5 V for a 8 Vpp short burst that goes into the negative as well.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=142674;image)

Last, when set to 0.5 V, the overshoot is very pronounced, but very short lived.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=142676;image)

Voltage is a bit high in the higher end (20.2V when set at 20.0V, 5.054 V when set to 5.0 V), but it's better in the lower end. (1.0065V when wet to 1.00V)
But it's just a bit under 1%.

I'm happy with it, I hope amc184 had a good deal as well with his.

Should I worry about the powerup spikes?
Title: Re: List your test equipment "scores" here!
Post by: VK5RC on March 20, 2015, 08:17:27 pm
@miguelvp Interesting re the power-on spike, I had one that was tripping the OV on a used 6644, the spike was only 8uS long but was 80V! The real problem with the 66xx etc series is they almost all use the SAME board FFS!!!!!! So half the component slots are not populated !!!!! and to make matters worse HP (God bless them) also skimped on the schematics, the schematics would cross two or three models, so the only way to know what was supposed to be there was the parts list, this was also clearly wrong as I had MOSFETs and the parts list had BPT!!!!
Long story short, someone had taken out a final filter cap and covered there tracks well!!! Aaaaarrrrgggghhh.
I wonder if you may be picking up other spikes via ground or radiative interference, but check the output caps for me please!

The mains turn on spike can also be caused by the in-rush current of the supply if your measurement method is inappropriate (where did you "ground" the negative post?)

A bit hard to judge at 10 ms/div...

I tend to agree. Leave the output completely floating, and use coax directly to the scope.  Don't create that ground loop by grounding the supply output.

Also to the OP, the meters are easy to adjust with multi turn pots on the display board. Yours seem pretty consistently 1% or so high.

I grounded the negative post to the earth ground post, the manual states that either the positive or the negative can be grounded. If I measure the voltage from the earthed negative with the scope ground (earthed as well) I get no voltage as expected.

I didn't want to ground the negative post with the scope ground to avoid transients.

Yes, the multi turn pots are nice and yeah I know I can adjust them, I was showing the voltages displayed vs output just for information, i'm not concerned about that at all.

I'll try to capture the transients at a lower time scale when I get back home.

Seeing the Tektronix CDM250 motivated me to take a photo of the CPS250 I got a few weeks ago. These are pretty decent power supplies, well suited for someone just getting started. I don't know who actually built these, but I read somewhere that maybe they were sourced from Topward.

Apparently BK Precision also sold this unit as the 1651. BK rated theirs as 24 volts at 500 mA from the variable supplies vs. the 20 volts of the CPS250, and 3 amps from the 5 volt supply vs the 2 amps of the CPS250. They seem to be identical to me, maybe Tek was just being more conservative with their ratings. BK still sells a 1651A.

These are definitely worth considering if you don't mind taking chances on used equipment and can find one in good shape for $100 or less. There are always people trying to sell these for $300-400 just because of the Tektronix name I guess. Don't fall for that. Also be aware that there are several different front panel color schemes. This is one of the better ones. The BK olive green and mustard brown is pretty bad.

Believe it or not, that's pretty much the way I received it. All I did was add a pot inside so I could dim down the entirely too bright power LED, and I switched the voltage and current control knobs with those on my BK 1651. The Tek's knobs had turned kind of brown and the ones on the BK were a better color match.

Same as most things which plug into mains power, they are fused. The fuse holder is on the back panel. For 120 volt service Tektronix calls for 2A 250V, BK Precision specifies 1.6A 250V. They are glass.

Are there any irreplaceable parts inside?
Are they difficult to repair?

The service manual is available. It's too big to post here but a google search should find it. Some things, such as the transformer and meters would be a problem to replace, but it's mostly jellybean parts. I think the only ICs are 741 and LM358 op amps, and 723 regulators.

It is, it's a 6 slot mainframe (I think that's what they call it). There are 2 doubles and 2 singles in it.

It needs a fan, but I have one ordered, and the programmable power supply will want calibrating, but for what I'm using it for, the 3456A will do for calibrating it.

I also got a precision bench source. It looks like it's controlled from a PC, as there are no settings on it, but it has a USB connection and an ethernet connection. I've plugged it into the PC, and it enumerates as a 'TTG-001 DC source', but no drivers are found. I can't find anything on the internet about it, and there is no manufacturer's name on or in the box, so I'm guessing it's a proprietary bit of kit for something.
I used Wireshark to try to determine its IP address but it's not being broadcast, so unless I can find how to control it, it looks like I'll end up robbing it for the power supply board and binning the sexy looking control board.

Chances are it speaks VXI-11 on the Ethernet side of things. Maybe USBTMC on the USB side of things. You can use something like arp-scan(1) to discover the IP. Probably in one of the private address ranges. imho looks too good / capable to just trash and take apart.

Very nice! I bought one of those TTi TSX1820 on Ebay a while back. It was broken but cost only about half that price.

I still haven't fixed it. ::)

I do have the service manual which took some effort to get from TT. Happy to send you a copy if needed.

Thanks... I'll have a look into it and see what I can find. I'm surprised there's no manufacturers name anywhere on it though.

I agree with you on it looking too good to trash. It would be a shame. I'll keep stabbing at it and see can I find anything.
It has a 16 pin header on the board that's probably a serial or UART interface of some sort. I'll see can I find what chip it's going to and pin it out, and hopefully access it from a terminal or something.

Cheers

Edit... I tried the ARP scanner and I'm getting no helpful results, so I'm guessing the ethernet port isn't configured.

Post by: miguelvp on March 30, 2015, 09:44:46 am
I got two old analog scopes for just $50 for both.
They've seen better days:
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=144290;image)

The top one is a Tek 7613 with 2 80 MHz amplifiers and a 100 MHz dual time base. One of the amplifiers has a broken voltage divider knob but luckily the broken off cal knob is in the cal position, so I won't be able to exit the cal value on that channel to make it fit on the screen but that's ok.

The bottom one is a Tek 5110 with two 2MHz amplifiers without a time base.

The only thing I've done so far is clean the screen and trim the gain and sweep on the 7613

Here is a picture of a 26MHz clock (OCXO) 5 Vpp using a x10 probe (so 1 V per division) at the maximum x1 time divider (50ns per division) if you notice I get 13 full cycles in 500 ns.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=144292;image)

Here is the same signal but using the x10 magnification in the time base module, so it's 5ns per division.
A 26MHz clock has a period of ~38.46154 ns divided by 5ns that will give me ~7.7 divisions.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=144294;image)

Goes to show you that back then you had to do the math to figure out the frequencies and you only could use the grid, DSOs are so much easier.

This one has storage and persistence but I rather don't use it, it's a pain.

My plan is to clean them up, maybe pickup some modules (for example 100MHz amplifiers)  for them and donate them to a local hackerspace.

The 7613 has a sawtooth generator in the back, that is controlled by the time division knob up to 560 KHz at the 50ns setting down to 18.73mHz at the 5s setting (takes over 50 seconds to do one period) and I can trim it to any frequency using the cal knob.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=144296;image)

This probably can used that to make a curve tracer using a different scope or maybe even the same one. Will have to revise alan's video (W2AEW) if I could use the timebase that affects the frequency of the sawtooth.

The crud on the screen was hard to dissolve (I used water and a bit of soap followed by my fingernail so I won't scratch anything), Also I'm not sure why both of them had some tape residue in the screen, it felt like hard glue, but believe it or not, it was harder to remove the splatter of who knows what.

Not sure what to use to clean the splatter on the rest of the scope without affecting the legends. Also not sure what to use to clean the BNCs they are crusty beyond believe.


The 2MHz scope is a 5000 series, not sure if I can get better plugins for it, but one of the knobs in one of the amplifiers broke, but it can take up to 60 volts AC or DC, I need a horizontal base for it or just use it to draw vector graphics :)

The 5110 calibration hook is 400 mV 4 mA 2x mains frequency (120Hz) :)

Not really a score since they are old and I already have a 7603 but has a bad dual trace amplifier.

Other than the sawtooth thing they are not that great compared to my Rigol DS2072, but for the price I couldn't pass it up and will try to bring them back to their former luster.

The PL330QMD (or QMT) is at the top of my shopping list. To bad most of the affordable ones are at the other side of the pond. With shipping and import taxes they are rapidly becoming unaffordable to me  :'(

Does anyone have one for sale, preferably in The Netherlands or Germany? I'm not sure what the shipping cost of a power supply like this is within the EU so I like to keep it 'local'.

Not really "scores", but they should suffice until the DS1054Z arrives:

DSO203 aka DSO Quad (Hardware-Version: 2.72 and already flashed with a custom App^^) for about 100€, including 2 Probes.

AND:

Philips PM3350 for 150€, without probes and a few quirks I have to solve (see this thread: https://www.eevblog.com/forum/repair/beginner-trying-his-luck-at-fixing-a-philips-pm3350/ (https://www.eevblog.com/forum/repair/beginner-trying-his-luck-at-fixing-a-philips-pm3350/)). But my first own real Scope! Yay! :)


I was first bidding on a PM3320, fully digital scope made by Philips with basically the same specs as the Rigol in 4-Channel Mode (200Mhz Bandwith on the Inputs, 250MSample/s), but someone beat me to it at the last second.
I then settled for this one, because I need Single-Shot capability, as well as reasonably high sampling rate to capture the reaction of a switching regulator (SEPIC-type) to load-dumps and sudden turn-on currents.

a few broken Fluke 287/289's for < $200 - then sent to Fluke and got repaired free of charge

A couple of newly CALIBRATED HP 1141A Differential probes for $220-250 incl power supply - great for bench work but absolutely not portable

Agilent N2792A 200MHz differential probe in perfect condition in original box etc  - looks almost unused for $350 (SRP about $1900) Great for my portable CAN work - Same price as the 25Mhz version usually goes for on eBay.

And the latest - an Tek MDO3012 with MDO3PWR and MDO3SA for $1900,- while that is not a great scoop - I sure look forward to it for my BLE stuff :) and the MDO3012/MDO3SA bundle is no longer available cheap as before. And came with a nice Pelican case and quite a few BNC adaptors. On route with DHL to me as we speak. Now looking for some 500 MHz probes and some Logic Probes (I wonder why.... :-/O )

These were given to my workplace from another department. Our department had never used them once. About 2 years ago the section I work in had to move to a different workshop and there was a mass clean out of unused gear. I grabbed a whole car load of old equipment.
In the attached photos are a HP 89440a vector signal analyser with the RF section, sitting on top of a HP 8753a network analyser. I have maybe turned these on ~ 5 times since I have owned them (once I zapped a cockroach who had found a new home in the VSA, thought it was the equipment itself so I opened it up to find charred remainders of the little guy)

I am currently considering selling the pictured equipment, along with some other gear I have acquired over time seeing as I don't use them (someone convince me not to!?)

The network analyser. Sorry for the average quality of the photos.

Edit: The "Calibration Not Required" sticker is because our department never used this bit of equipment so it was given that sticker to not confuse it with all of the equipment that did have to go for annual cal.

7A11 (was missing the pull tab so I used one from a 7A15A) , 7A13, 7B53A

Also I got another 3 modules coming for another $36 including shipping.
7A18, 7A26 and 7A22 (last one missing the pull tab)

Plus the last one three times more expensive is a 7D15 225MHz Universal Counter/Timer for $36.

I have a few goodies to share, first up is an Advantest R6161 voltage/current source.

A bit of a sick puppy though, only the 1V,10V,100V ranges work, I'll do a teardown when I repair the thing. I have a feeling the relays are shot. Thank goodness the voltage/current limits work just fine, because if I dial in anything on the 1000V range it instantly shoots into the set voltage limiter (not so fun when I set the limit to 1050V and dialled in said 5V to test the range).  :-\

(http://i.imgur.com/AfHaTF8h.jpg) (http://imgur.com/AfHaTF8)

Next up is a Panasonic VP-7722A audio analyzer. I'm kinda sorta into audiophoolery and I had no idea Panasonic used to make these things until recently! It's actually quite a respectable performer too, 0.00025% THD+N 2.5V @ 1kHz, 30kHz BW. It weighs a bloody ton at 17kg, might need to start a new thread for a proper teardown if anyone is interested.

I'm super impressed by the unit, because while it won't spit out pretty FFT's which are all the rage these days, I think it will be very handy for quick and dirty production line testing since you don't need a computer to operate it. It will happily dance with 'entry level' Audio-Precision analysers, I think you need an AP 2722 ($10k+ used) to better it in terms of THD+N anyway.

It's insides are so colourful, having modules and right angle pots make it easy to service/calibrate.  ^-^

Yep, those are digitally controlled analog analyzers much like the venerable HP 8903. Interesting thing about the Pana analyzers is that their source sections are truly floating ; although for 99.99 % of all usage scenarios a proper differential output would be just as well usable. They are available under at least three brands (Panasonic, National and Matsushita). There are some other models in that line up, namely VP-7721A (no GPIB iirc), VP-7722A, VP-7723A, VP-7724A, VP-7725A and VP-7726A. There are also *B variants. The higher the number the newer.

Wow that's neat, thanks for the info.  ^-^

The 7722 and 7725 has the lowest THD+N from the research I've done. I'm on the lookout for the 7725 to see if it performs any better than the -22. It's specs are about the same, it just has an LCD screen. Maybe I'll complete the happy family one day. XD

Not exactly a huge score, but after some uncertainty, I'm pleased with the Keithley 2000 I got on ebay for ~$250.

First impressions was that it was packed quite well. The VFD was bright, and the voltage readings off my Chinese AD584KH based voltage reference were quite close to the numbers on the references "calibration certificate." It was also a sickly beige  :-\

At first I thought it was from aging of the plastics, but when I opened it up, I was met with the smell of stale tobacco smoke. Fortunately, it hadn't accumulated enough to leave a visible film as it had on the outside. I also noticed that at some point the motherboard had been removed and then reassembled by a meathead. Cables to the front panel and power supply didn't take advantage of a clip intended for them on the side of the chassis. More concerning, the main PCB was flexed because they'd forced the front right corner in over the guide/support tabs on the chassis. In the process, they managed to scrape the solder mask off a grounding trace.

Once I'd reassembled the device properly, I ran the self-tests and was disappointed to see the failures cascading off the very first test, 100.1, which checks to see if the A/D converter's 0v reading is in range of the design specs. The repair manual wasn't very helpful (it doesn't identify the signals on the various test points, and doesn't even bother explaining how to get the device to display the measured value for each test (When you run the tests manually, in step mode, pausing after each test, you can hold down the shift key to see the measured value). I finally got fed up, found the reverse engineered schematic online, and started orienting myself to the signals on the A/D converter IC by probing each lead with my scope. As I shifting the device on my desk to get a better view of the leads on the side of chip closest to the right side of the chassis I noticed a bit of white. At first I thought it was silkscreen priting, but it seemed misoriented and out of place. I looked closer and it seemed to be a small fiber of some sort. I flicked it away with my gloved hand and then blew the area clear with some canned air.

All the tests passed!  I'd like to blame the contamination on the meathead who did such a bad job reassembling the thing but there is a good chance that it was a stray piece of pet fluff from our dog. (Once again, I've managed to fix a piece of equipment simply by taking it apart, looking at it, and putting it back together).

From the date codes on some of the components and the date on the one and only calibration, it appears that my multimeter was manufactured in the latter half of 1995. Probably a good idea to replace the electrolytic caps at this point? I'm also going to try and clean up the outside more. Any tips on dealing with the tobacco stains on the rubber/silicone buttons?

@eas

I have already recapped three Keithley meters and I would say you should change the caps. TiN has some good pics of the hidden damage that can happen with no external signs of damage. I have two of three with some damage to the pcb and traces. The third was showing some leakage with no damage. I have a fourth that is waiting for me to finish the epoxy repairs. I have also been replacing the Schurter input power modules. It is easy once the board is out for cap replacement. There have been no reported issues yet, but there have been failures with the Schaffner modules of similar age.

I clean all keypads with ipa once I have the front panel removed. I also clean the pcb contacts. You never know what has been spilled into the front until it is taken apart. It is also a good time to clean the VFD display and the back of the lens. Simple Green is good for any stains that are hard to remove.

Thanks. I'll probably re-cap and replace the input power modules after I get through recapping my Power Designs power supplies.

I've cleaned the front panel inside and out with IPA. I've tried cleaning the buttons by soaking in both IPA and dish soap and water. Unfortunately, the tobacco stains seem impregnated the rubber keys. I'll probably try giving them a longer soak when I have it apart for recapping. In the meantime, I'll keep my eye out for anyone selling front panel parts for the right price.

I'm really glad this thing didn't have any ventilation holes, or I'm sure the inside would be coated with a thick layer of tobacco varnish

Been debating getting a Brymen BM869 as I really wanted a higher quality DMM in my toolbox. Been mainly using my UNI T 61 for low voltage electronics and besides a few annoyances it's actually been pretty good.

I've been also looking at a Fluke 87-V but at $360 I feel like it's a bit too pricey. So I just randomly stumbled on Ebay and found someone selling 5 87-V brand new for $275. I had to have it.

http://www.ebay.com/itm/191569718741?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.com/itm/191569718741?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

So I guess that's my score a $275 brand new 87-V Fluke for the price of a (Fluke 179).

I picked up a "used" HP3450b a while back for $50.  This is still fairly impressive (0.003% + 0.001% of range for 1v - 1KV 24hr spec) and the nixies are just kind of cool.  However, somebody had pulled the display board, so I got a $25 credit and put it aside.

The other day, I saw an ebay ad for "8 nixies on an hp board for retro clock".  Hey, that's a 3450 display board!  So I sniped it for $30 and got it the other day.  Plugged it in and it came to life ;D  Shorted the input and it settled down to a couple of microvolts after a few minutes.  Still need to run it against my Fluke 332b and compare with the 3456a, but it looks like the basic functionality is there.

Some stuff I picked up this weekend for $100:

Fluke 8600A:  Seller stated that following doesn't work: No AC functions/ranges, all DC voltage/resistance functions/ranges, and the 200mA and 2000mA DC voltage options. 

Going to find a manual, borrow my buddy's better DMM, and then get to work on it. 

HP 3311A Function Generator:  Said the waveforms are distorted.  I downloaded a copy of the manual from Agilent but its a piss poor scan :\  Looks like I'll be getting one from Artekmedia.

Tektronix 2225: Was told it has a vertical amp failure.  Downloaded a scan of the manual so will print it out.  I goofed around with it today and channel one can display various waveforms from the function generator I purchased, although channel two has something wrong with it, it displays but adjusting the volt/div doesn't provide usable results on screen.  Hopefully repairing it won't be too large of an undertaking, and then I'll have a older Tek scope, and I've always wanted one.

Not really test equipment, but I was looking for a sheet of toughened glass to top my bench and guard against scratches.  I was going to buy one, and went to the dentist in town and noticed their neighbour they had a dirty rusty TV stand in their front garden.  It was the type which has 3 glass shelves so.....  I knocked the door and asked for it.  They were well pleased to get rid of it.  A little washing up liquid and the glass came up pristine.  So now I have 3 sheets.  And the cost?  Nuppence.

I bought an HP 6632b off of eBay a little over a week ago. It was listed as "for parts/repair" because the seller was unable to test beyond powering it up. I got it for $99 + shipping from TX. They had 9 more. I thought about posting about it here, and I was tempted to buy a second, but I decided to wait for both until I had a chance to check out the first unit.

I kept checking the listing to see if the remaining units were selling, and someone else picked up a unit, but as of beginning of last weekend, there were still 8 left. And then, suddenly, they were all gone. Someone bought all of them, for a best-offer price. Doh!!

Too bad, because, while mine was a bit banged up, the insides looked good, and the output works and is fairly accurate, so far as I've tested it.

Actually, when I say the insides looked good, I'm leaving out and important detail. What I should have said is the insides looked good, for a 15 year old unit that seems to have spent its best years in a LINT FACTORY.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=151864;image)

Its a little hard to make out in the photo, but there are huge tufts of lint stuck around all the ics, snarled in leads, and heatsinks, even the area between the case and the front panel.

No connections at the front of the PCB for front panel binding posts, unlike some of the examples people have.

UPDATE: Ok, so apparently there is a 6632b option with an order of magnitude more lint (http://blog.narrat1ve.com/2010/07/02/care-and-feeding-of-the-hp-6632b/) than I got in mine. Now I feel cheated.

I bought an HP4274A LCR meter but I have not received it yet. The reason for buying this old clunker is because it can deal with high (external) DC bias voltages and has a 100milli-Ohm range which makes it ideal for measuring Li-ion batteries and testing ceramic capacitors. A more modern LCR meter with similar specs costs several thousand euro/dollars which is more than I want to spend right now. I got a bit inspired by the recent 'LCR choice' thread.
The Ebay auction said it has errors but according to the manual they are caused by a dead battery and nothing being connected to the test inputs so fingers crossed!

You have what was called the 'soft keys' option.  I have two 3456a meters and love them because of the red LEDs.  I like them more than my pair of 3457a meters, one of which I have listed on the local craig's list for just that reason, hard to see with my limited vision.

My most recent score was an Hp 34401a 6 1/2 digit meter.  It was part of a "for parts" lot with a power meter, listed as doesn't turn on.  I paid $70 for the lot.

After spending a few bucks on parts, it is now a perfectly functional meter.

The reason it wouldn't power on?  It was missing the fuse.  Along with a fuse cap for the amps fuse, and a new display lens (total parts cost approx $50), she's as good as new  -- I didn't even have to open the meter.

After seeing a lot of scores here, some of which made me a bit jealous  ;) , I have scored some nice equipement yesterday.

At my uni they had some RF related test en measurement gear they want to get rid off. I've made them an offer and to my surprise they said 'Oke'  :-DD

Here is my score:

- HP 8590A Spectrum analyzer - 10kHz-1.5GHz
- HP 5315B Universal counter - up to 100MHz
- R&S AFG Function generator - 10mHz-20MHz
- R&S SMP02 Signal generator - 2GHz-20GHz

I've tested them all and as far as I can see they are all working as advertised and are within specs.

To make the story almost to good to believe...... I only paid €345,- for the lot.  :-DD

For all equipement I've found manuals except for the R&S AFG so if anyone has this as pdf, would you be so kind to share?

Not as great of a score as some of these, but I'm pretty happy with my latest acquisition so far.
It's an Advantest R3162 spectrum analyzer with the tracking generator option for $850 USD.
The only repair needed was a new battery on the CPU board; once the battery was replaced, the analyzer passes all self-tests and self-calibration. 

While I had the thing apart, I noticed that it uses a compact flash card for firmware storage, so I figured it'd be a good idea to make a backup of the card.  I was glad to see a CF card rather than a mechanical hard drive.

I had been planning to pick up a Rigol DSA815-TG, but this Advantest is an 8GHz analyzer (TG goes to 3GHz).
Next will be to see if one of the USB stick floppy drive emulators will work in it; not strictly needed, since I can probably do screen grabs over GPIB.

I saw a HP 3456a come up on e-bay, ended up winning it for $63USD + $27USD shipping to Australia (I think someone stuffed up the figures there. I don't know the weight of these things, but I know they are huge). Listed as for parts or not working. Every listing on their account is for parts or not working, so they buy, don't even plug in, and then sell. It is a bit of a gamble, but at that price I am willing to risk it. Now to find a home for it on the bench with the 2 3478's, 3457 and keithley 2015.

Edit
I just checked the paperwork and it is being sent out via e-bays global shipping program. I know that program is quite expensive so I am going to guess that the seller hasn't put in the correct dimensions or weights. I wonder who has to pay the difference once they realise.

Not sure as it doesn't mention anything about free shipping. Maybe because I'm in Australia it doesn't mention it. I've attached a pic of the listing so you can see if it is the same one.

Been chasing an analog scope with some decent bandwidth for awhile now. And really wanting a Tek 2465B but haven't been able to find one that looks in a good enough condition and also isn't too expensive. All the ones that look clean are overpriced imo. I mean it makes sense, it's considered one of the best analog scopes ever made. It's just some people want exuberant prices for them.

I looked at some LeCroys, and I found some that I liked but they just seem too big. So I bit a bullet and got a HP 54610B. Really like its form factor, since it's not going to be my main scope, just something to measure fast rise times on repetitive signals. Also I am a sucker for retro looking green CRTs. It will serve as a channel expander to my rigol dso2000 and it can still capture some single shot stuff at a measly 20Ms/s in a pinch, if I need to monitor a slow non repetitive signal (things like chip selects on SPI come to mind).

Also there is very little posted about them so I might do a tear down post.

It was an as-is deal so hopefully fingers crossed it won't require repair. Cosmetically at least it looked to be in great condition. One thing that worries me though is the front end. While I hear it's excellent. It can only take 5V in 50ohm mode, so the channels are fragile enough to be fried. However in reading the manual they mention that they have auto protection from over voltage, so maybe not, we shall see.

Bought a General Resistance DV-4107 Kelvin Varley Divider. A look of the inside shows that the resistors are matched, coded with batch numbers and serial numbers.

It appears to be linear down to 1ppm which is as good as I have a use for. If it is actually 0.1ppm good, I need better equipment to need it.

Don't know why I bought it, maybe boredom, but I picked up a really clean HP 3852a with 5x FET scanners and a high speed volt meter for $50.  Works perfectly.  I then bought the ARB waveform DAC for it on eBay for $13, a relay accessory as well as the integrating volt meter, all for under $20per.

This thing is amazing.  I could wire my entire house, actually the entire hood, if I wanted to use it as an alarm.  Each FET mux of which there are five, has 24, two wire ports.   The high speed volt meter will do 100k measurements per second and can be used to load the arbitrary DAC.  I found code for the DAC that will do all kinds of waveforms out to about 200k square wave. 

If I ever figure out an application for it, at least I'll have one...  :-//

Happy to share. I believe that the resistors are ridiculously labor intensive and expensive to match into groups for each decade. When I had the 2002 DMM it showed me that each resistor in a decade is just about exactly the same ppm above its nominal value. The string for the decade measures 10X the bottom resistor including ppm deviation from nominal. Research says that it was probably built in the 1960s. I bet they used a very good bridge to match the resistors.

I am very happy to have acquired it. I think that if I can get another one and place the inputs in series, I can use the pair to measure 1000V. The individual unit is rated at 700V max.

This is a Fluke 731B that arrived this week. The 10V output was low 18 ppm so I adjusted that up. The 000 to 999 delta-E was jammed. I removed the dial pot and found that it was just pushed in too far and that jammed it. I followed the instruction manual to re-seat it and it works perfectly. The rear panel is badly dented, not a big deal. Battery is missing, I shall build a new pack.

Delta-E, mostly on 00.00012, bounces to 00.00011 occasionally.

Attached is the D-version manual with specs. That is all the presently owning company has. I was glad to get this.

I paid $50 shipped. It was a bargain to say the least.

This is more of a 'kids these days' sigh than a score. A friend who works in the education dept gave me three soldering irons. They'd been tagged Unsafe by the electrical tester guy. Because... the kids had applied the soldering irons to the soldering irons. The plastic cords and stands.
There seems to have been a contest to see how close to the iron the iron could burn its own cord. See 2nd pic.

He also had a nicer model from the same source, disposed of for the same reason. I fixed that for him with a bit of plastic welding using some scrap plastic of about the same color as filler, then filing the surfaces flat. Looked much better without all the tip-melt-holes through the case. Didn't think to take pics of that one.

These three, I'll do minimal repairs and keep as spares.

It just happens and this is in fact one of the reasons why here (at least in my fed. state, but I assume the others handle this the same) only low-voltage irons are bought for schools.

Btw. are these really irons with 230 V heaters, or did the manufacturer just use normal power cable to connect the iron to the base?

I believe they are 230V and a triac in the base station switches the heater to change temperature. There is no feedback from a temperature sensor, just open-loop heating.

It is a school. You know, a place where (some) kids learn about stuff, sometimes by doing stupid shit. You may have come out of the womb fully formed, in which case, its probably futile of me to get you to realize that most people take a little longer, but most people take a little longer. In fact, for most males, it takes about 20-25 years before good judgement really settles in. Most women are a little quicker, but by the time they are 20, they've had plenty of chances for poor judgement with respect to men and contraception. And so, a new generation is born...

At least the kids can be thankful for the modern electrical protective devices, which reduce the risk from them doing this to a lower level. Think of the first electrical circuits, where there was no such thing as the fuse, which was only invented later, and where there was no such thing as RCD breakers either. The protection was there for the wiring, so as not to have a fire caused by overheated wall wiring. Did very little to protect against electric shock, and did little against faulty equipment causing a fire or killing you.

Just scored a Tektronix 1735HD Waveform Monitor at a garage sale for less than $10.
Originally I thought it was a scope, which I need and this would have been a great deal but it's for measuring/monitoring video signals.

Plugged it in and thought the CRT was not working but after a bit of fiddling I found the trace off the screen.
Passes all internal tests so I'll probably sell it and I'll have to keep looking for a scope.

Hi Folks,

Just unpacked my Keysight 34465A meter and had a play on it, notably faster update than the '61A but totally awesome 1uA current range. Also, I purchased a new Tenma 72-7245 twin 30V 3Amp power supply, what a joy to use. Regulation is around 0.01% that's voltage source spec.,eh?, this psu is a rebadge GW-Instek (made in Taiwan)  :-+, two notches up on standard Chinese quality.

Gotta really nice deal on an HP E3611A. Someone spilled black ink into the case though. Wasn't much but it spilled on the heatsink around one of the big bipolars. Cleaned it up, put it together and works like a charm. It's running a little high (100mV) so will have to calibrate it at some point.

Well it was time to upgrade my soldering situation. Shopped around and assembled a Metcal mx500 soldering system. Got a brand new handpiece and tips, everything else 2nd hand.

edit: ok so I got my Metcal mx500. And wow. The hype is justified. I literally just touched some pads with the sharpest/thinnest tip and they were soldered. Instant heat transfer! I had no flux on the pad, and I wasn't applying solder, just applied some solder to the tip ahead of time, which usually doesn't always work the best (flux is long gone from the solder this way), so I did it as a test. The wire I was soldering to the PCB pad, instantly made a bond. Like I just touched it, didn't even press to make a contact.

My Hakko is pretty good, but this is like magic. Very impressed, should have done this long time ago.

Tek P5205 100Mhz High Voltage Differential Probe plus P6243 1Ghz 10x FET probe for 160Eur :)

5205 had broken contacts inside both 4mm connectors, apart from this it works perfectly! Replaced the (very stiff and hard to use) input wires with nice double-insulated silicone ones, and soldered on new MC insulated 4mm connectors. Thats it, the best diff probe ive used so far.

6243 wasnt even mentioned in the auction (the picture did show some other cable with Tekprobe connector not belonging to the 5205), had the cable broken off at the probe end.Ths was NOT easy to fix, as the probe itself is very compact and contains a ceramic PCB with completely un-protected wirebonded die and gold metallised traces.Tekprobe Connector box is empty except for an EEPROM identifying the probe. VERY easy to damage a wirebond or dissolve a trace by soldering! Luckily i could reattatch the cable and it also works fine now. Gonna sell it though, as i dont need it.

HP 34970A 6.5dig DMM/Scanner/Data Logger, with 1 20channel Mux card for about 100$
Didnt do anything, totally dead.PSU seems fine, but the 3V Lithium battery was at zero volts, after applying 3V it did boot fine! Replaced the battery (14250 size), works fine. Nice instrument! integrated DMM is based on the 34401.
Still strange a faulty battery would cause the unit to fail to boot up at all...

Strange indeed, unless the battery had actually failed short circuit. Two weeks ago I bagged one of those, sold as working, for £185 with a 16 channel high-speed mux card. The battery in mine was pretty much dead (about 0.6V) but the unit booted fine, it just gave 'memory lost' and 'time lost' errors. Maybe you had a loose connector somewhere that got 'mended' when you took the DVM module out to get at the battery?

These are great instruments - one of HP's lesser-known gems. On the 10V range, mine agrees with my 34401A to within better than 10 microvolts on the 1V range. Neither has been calibrated in years. We use dozens of them at work, generally wired to large numbers of thermocouples and monitoring DC voltages during temperature sweep testing.

Last Friday I checked eBay and noticed that two different sellers had done big temporary price cuts on HP 6114a precision PSUs, and one was asking $75 + 19 shipping. I already have too many repair projects, but I was also intrigued at the chance to get one of these for a good price. So, I offered $55, and they accepted it.  It arrived yesterday.

The HP 6114A is in decent shape after some clean-up and body work (http://techobsessed.net/2015/08/hp-6114a-precision-power-supply-first-look/). Now to put it back together and see how it works.

Suggest taking the wheel switches apart and give them a good cleaning. When these switches are noisy, problems with the output can occur.
That entire area must be really clean as leakage paths can also result in problems.

Yes it did survive. All functions work. The energy of hitting the ground was absorbed by one back corner zinc leg. It fell off with destroyed threading. So I am confident that rest of device is OK.

Keithley 2000 - $100 - eBay (Some woman who had no history of test equipment purchases or sales, no idea where she got it, but aside from a yellowed front panel works perfectly.)

Tek TMO503 Three Slot Power Module with PG506 Cal Generator, TG501 Time Mark Generator and SG503 Leveled Sinewave Generator - $80 - eBay

The whole thing turned out to be in rough shape; the modules were all erratic, which turned out to be an issue with the power supply. I replaced a diode bridge and all the caps, added BNC connectors on the back and scrubbed the chassis clean. Works perfectly now.

I also disassembled all three modules and scrubbed them clean, reseated all the ICs and lubed all the pots and switches. The SG503 turned out to have two broken contacts on the cam switch, switch I found replacements for. I broke a BNC connector off the PG506's fast rise board, which I'm trying to find a replacement for; I also replaced all the 74-series ICs with new LS versions. As for the TG501, everything works perfect expect for the 2ns and 1ns modes. I'm currently trying to fix that.

Cosmetic wise, the modules look really beaten up; broken levers, chipped corners on the faceplates, etc. But considering these were all made in the mid-70's, still work and are all in-cal, I can live with it. :D

Thanks.

It seems to be working Ok at first blush. I'm going to calibrate it and then check more closely. I'd rather not take the switches apart if I don't have to. They aren't made for disassembly, and even if they were, it brings a new risk of breaking something. I already have enough things to fix that don't work at all. :)

- HP 5315B Universal counter - up to 100MHz
- R&S AFG Function generator - 10mHz-20MHz
- R&S SMP02 Signal generator - 2GHz-20GHz

I've tested them all and as far as I can see they are all working as advertised and are within specs.

To make the story almost to good to believe...... I only paid €345,- for the lot.  :-DD

For all equipement I've found manuals except for the R&S AFG so if anyone has this as pdf, would you be so kind to share?
Those pictures are familiar. Does it happen to be HAN university of applied sciences in Arnhem, Netherlands?

If so: you lucky man. I thought of making an offer but they also said they already had a company buying the lot. That SA alone goes for more than twice on eBay than what you paid for the lot... <insert green face here> ;)

Still: congrats!

The R&S SMP02 is probably the most expensive unit in the score. Easily more than 2000$,if you find someone who needs it. US ebay has them listed between 5-17k$ and you get it for 350€, holy shit

I'm still looking for something comparable to realign the YIG input filters of some HP 8566s that I'm rebuilding. Wish I could get one for 350€

I'm still mulling over whether to disassemble and clean the decade switches, though at this point, I'm leaning towards putting it together and power testing.
Suggest taking the wheel switches apart and give them a good cleaning. When these switches are noisy, problems with the output can occur.
That entire area must be really clean as leakage paths can also result in problems.

Bernice

Thanks.

It seems to be working Ok at first blush. I'm going to calibrate it and then check more closely. I'd rather not take the switches apart if I don't have to. They aren't made for disassembly, and even if they were, it brings a new risk of breaking something. I already have enough things to fix that don't work at all. :)

A few small adjustments and the 6114a is appropriately accurate on most settings. 10mv decade is a bit inconsistent and noisy though. Next step will be cleaning the board of any flux residue from when I removed and then reattached it. I'd really like a 10-turn pot for the low adjustment too, but that seems a tall order.

In other news, this weekends OMG buy is a EDC 521 programmable DC calibrator for $150 "from a working environment." The seller has some other EDC gear listed (http://www.ebay.com/sch/m.html?_odkw=&_ssn=seaviewtech&hash=item3f52339cf8&item=271962053880&_osacat=0&_from=R40&_trksid=p2046732.m570.l1313.TR12.TRC2.A0.H0.XEDC.TRS0&_nkw=EDC&_sacat=0), though not at as low a price. It's all listed in the wrong category, and its kind of chance that I saw any of it.

Do check for possible residual paths that can be causing the observed noise. Use high purity (electronics grade or similar) Isopropyl alcohol. Lower purity solvents can leave residuals causing problems.

Been there done this, when those switches get noisy, the set low range accuracy suffers and the output can be noisy too. That 10 turn pot works when all is well. These are good precision power supplies.

I'll try cleaning it up. I know there was a drip of RMA flux that ran further than I'd like, but I forgot about it in my drive to actually get the thing powered up. Thanks for the benefit of your experience, without it, I'd probably put this supply in the good enough for now category.

As for the pot, I meant finding a small 10-turn 20 ohm precision pot to replace the small pot on the >=mv adjustment was probably too much to hope for. If you have a source though...

I plan to replace the current pot with a 10 turn, but I don't anticipate that will be a problem, and I've already ordered a black kilo turn counting knob for the upgrade.

Looks like someone gobbled up the EDC 1030 the seller had listed for $400. I guess I'm not surprised that one went next. I considered it, briefly, but an AC and/or higher DC standard is worth more to me than covering the 1000v DC range.

It's no super quality there is lot of distortion over 10MHz. Let's see square wave at 30MHz.
But up to 10Mhz it's usable. And up to 50MHz as signal generator.

Agilent N1996A .1 to 3000 MHz Spectrum Analyzer like new for less then the price of a Rigol DSA815-TG. I then used info on the forum to enable all of the extra features such as Histogram, Response Stimulus(the tracking gen), the modulation analyzer and AM/FM demod. Once that was done I couldn't help but experiment with the band "limits". Agilent makes a .1 to 3000 MHz unit and a 0.1 to 6000 MHz unit. I made a few tweaks and mine now magically works to 6 GHz. By default the tracking gen/stimulus package starts at 10 MHz but I changed that to 1 MHz and it seems to work fine there as well. A little advertised feature in the unit is a fully internal/automatic full bandwidth return loss bridge. No additional hardware needed to do return loss/SWR from 1 to 6000 MHz - total score for a ham radio guy.
Here are a few fun shots, one of my HF antenna, the other of a dual band wifi antenna.

I have purchased quite a few bits from eBay over the past two years as I have entered the EE arena.

I got a an Agilent 6653A 500W power supply 0-35V 0-15A for about $400 which I thought was decent. The 6653A is a fantastic power supply. The real score was a month or so later when a found one for "Parts or not working" and got it just under $200. When I received it, there was indeed no voltage at the outputs, but cosmetically in good shape. I took off the cover and started hunting for obvious problems. I used my known good 6653A as a reference and everything was checking out ok. There were no self-check errors and all voltages on the PCB were just fine.

Eventually, I noticed the screw that attaches the output terminal to the Main PCB was loose. I tightened the screw and all was just fine. It has been in continuous use ever since. The user interface on these are not all that great, but I have them being controlled over GPIB now so it does not matter. They are super clean and have a good dynamic response. Sense lines are very handy. I would not trade these for any other supply in the same range. New cost is well over $3,000 US

I snagged two Fluke 8800A's 5 1/2 digit multimeters and a Velleman PCS500 2 Ch 50MHz parallel port connected PC Scope going to the dumpster at a local college.

The two Flukes were noisy on all functions and ranges. Both meters had identical failures of the 50uF 50V caps in the 35 volt power supply. Replacing all the caps in power supplies brought both meters back to life.

The Velleman PC scope had classic 120Hz ripple and would not auto calibrate. You guessed it!
A dry 1000uF cap in the wall wart power supply repaired all the faults.

Slightly damaged HP 8566AB for 350€ delivered, probably a dumpster dive rescue some time ago. Dude who sold it to me bought it for parts, but never used any of it, so I got a complete unit.

Since it#s a 8566AB, it has MC68000 retrofit instead of HP9845 CPU, so there will be no problems with unobtanium CPU.

Front panel is  quite smashed up, but that (polystyrene if I'm correct) plastic can be epoxied quite well and I can salvage a new front frame from a 85662A that probably took a bath in the dead sea. (bought unknowingly from that stupid israel guy loooong ago, before those pics of those bulldozed handheld DMMs were online)

Apart from smashed front panel, it's complete, hopefully there is no toasted input mixer or damage to the YIG oscillator. Will find out soon...... Else I have parts unit for my other 8566s.

BTW I need to stop collecting old spectrum analysers, since that one is 8566 #4   :-DD
And I need to get a microwave sweeper/synthesizer with power meter to recalibrate YIG filters

I'll see how much work it needs when it arrives (if it arrives -- the seller's account goes back a couple years, but only sold their first items a couple days ago).

The seller (http://www.ebay.com/usr/mousemr2?_trksid=p2057872.m2749.l2754) has some older HP/Harrison supplies available for similarly low prices.

Received a Tek CFG253 signal generator from an Ebay seller. Nothing really special about it, the stamp on the inside of the case is dated Oct 1997. The thing is, this unit has got to be new old stock. I mean there isn't a trace or indication it's ever been used, barely a speck of dust on it, not the slightest scratch in the case, no signs of any human hands ever adjusted any knob. On the inside it could pass for coming straight off the assembly line. It even came with a line cord still sealed in the bag - it has to be the original. I don't know where these things come from, but they're out there still.

What I'm doing with it is keeping it with the other Tek models that stack up together, so I can possibly give them to my nephew, if I can get him interested in electronics.  Hahaha :-//

Besides square wave, which I think is pretty good, the signal generation is really nice. You can modulate AM, FM, sweep generator and all sorts of cool stuff all the way up to 50MHz!

My new 8566AB now works nearly flawlessly, only a few PLL unlocks, but that's probably all fixable.

Removed damaged front panel and installed replacement front frame from old 85662A. Since the metallisation beneath the paint of the damaged front panel was flaking off, I decided to strip all that stuff and dumped the panel (plastic only, all metal except the brass screw nuts) into a bucket full of dilute sodium hydroxide solution (prolly about 5-10g/L).

I thought that the metallisation to be aluminium, but it isn't (probably nickel, but not sure). Thereby the process is very slow (aluminium foil is quickly eaten by that solution). But it still gets dissolved somewhat and the metallisation layer can easily be stripped with high pressure water jet cleaner after the panel spent a night in hydroxide solution. No harm to the plastic whatsoever (solvents will probably harm the plastic).

Since I couldn't wait, I borrowed a front panel from other 8566 and installed it. But new 8566 was dead, both red LED were on. So I checked voltage rails (only with Keithley 2015, dumb idea), +5.2V rail was at 4.3V, so there's must be a tantalum cap short somewhere, I thought and started to remove cards. But with all cards removed, both red LEDs were still on and 8566 was still completely dead. So I swapped CPU cards from good unit, but still dead unit.

Then I decided to check voltages again but used trusty Tek 7904A with 7A13 this time. And big surprise, the 4.3V on 5V rail turned out to be more or less 100Hz AC from rectifier, with 4.3V DC content. Which means that this biga** blue 30000uF cap on the 5V rail is completely dried out. Don't let size foul you 8).

That computer grade screw terminal cap has a date code of 1982, week of 01 or that cap lasted about 30 years. Not too bad for service life.

The PLL un-locks should be quite fixable, problem can be dead tantalum caps to out of value resistors related to the YIGs or dirty connectors. Suggest try cleaning the connectors first, then moving on the caps and ...

After a good going over and cal, it should be good for a few more decades of service.

Great to see another hp 8566 put back into service. ;)

My new 8566AB now works nearly flawlessly, only a few PLL unlocks, but that's probably all fixable.

Then I decided to check voltages again but used trusty Tek 7904A with 7A13 this time. And big surprise, the 4.3V on 5V rail turned out to be more or less 100Hz AC from rectifier, with 4.3V DC content. Which means that this biga** blue 30000uF cap on the 5V rail is completely dried out. Don't let size foul you 8).

Now only need to fix that front panel and find out, why those 2 PLLs refuse to lock.

My HP 6114a showed up today.  Other than some sticker residue and missing front feet, it's in perfect condition and even works.  :-DD

Pretty good for $60.  Now I can throw away one of those crappy PSs I have.  I'll still replace some of the caps though.

Bought a defective Philips PM6661 automatic counter for 10 euro. Looks to be in a nice condition. It's probably the most cute gear in my collection.  :-DMM May not be a great catch to some of you, but in Europe measurement gear seems to be so much more expensive than in America. Too bad shipping costs from America to Europe are expensive.

Will start troubleshooting tommorow.

Man, it looks snug as a bug with it's friends in the background.  Nice fix and nice collection.

Thanks,I'm too quite happy with my collection. Mostly/nearly all bought cheaply broken or untested and repaired. If I'd live back in the 80's with all that gear, I'd probably be a test gear millionaire, considering the catalogue price of that stuff back then.

Nice collection I see I have some catching up to do . :)

The cutieness of the 6661 is probably the only reason why it usually sells for 60-90 €... :)

Very happy with my latest score.

An HP54701A 2.5GHz FET probe for my scope - only $75  :-+

Its in pristine condition, with a tube of spare tips too which are expensive little hens teeth.

Works like a treat too - it was a punt on eBay for a "Parts, not Working" listing.

Almost fixed it. One bad hcf4556pc with a shot output messed up the LCD. Quite an easy to fix device, everything is accesible once the case has been removed. Leaves me with one bad input fet wich needs to be replaced, it makes lot of noise above the 10MHz range. You won't believe how stable and fast this little thing is. Its just as precise as my HP5316A, just 1ppm off to our calibrated waveform generator (PM6661 is uncalibrated). It was made halfway 1976.

Nice and congrats!  I just got a 3577A with the 35677A test set for a good price.   Love it!   :-+  I've been trolling the bay for one of these for quite a while now...

Once I receive a 2m GPIB cable for it I'm going to see if I can put together some python-vxi based software to grab trace data (D1,D2) off of it.  Will post when I have something working!

It's a sweet little machine!  Not too many VNAs that go down to near DC these days, which seems to have become the domain of impedance analyzers.

My $150 Krohn-Hite/EDC 521 DC Voltage/Current Standard (http://techobsessed.net/category/repair/edc-521/) arrived yesterday.

It is huge (20" deep), but not heavy. It has a tear in the red filter over the LED display that wasn't obvious in the eBay listing, and the bottom panel had a big-ass dent. Inside was covered with a layer of persistent dust.

I hammered out the dent using some hardwood blocks, cleaned the insides out with IPA, and checked for damaged components. I didn't find any, so I powered it up and it works!

(http://d112tss1dzpest.cloudfront.net/wp-content/blogs.dir/22/files/2015/09/IMG_8647-e1441234996930-1024x515.jpg?323d81) (http://techobsessed.net/category/repair/edc-521/)

The manual gives a 2 hour warm-up time. The photo was taken a few minutes after I powered it up this morning. At that time, my Keithley 2700 (powered on for ~20 min, not calibrated in years), read the output as +9.99973v, for +10.00000v after a few hours, the reading settled in at +9.99990.

A quick check of the 100v and 100mv ranges looks pretty good too, as did a quick check of the current settings. I'm logging ~24 hours of readings right now. I haven't tried the GPIB programing yet. Assuming it works, I think I write a little script to cycle it through every output setting in every range and log the measurements.

While doing the initial inspection, I noticed that there is a revision to the circuit, with some added resistors and caps, a cut trace and a bodge wire. It also looks like some power transistors were replaced at some point. The device seems to have been built in early 1997, and most of the parts are from 1996. I couldn't find/see date codes on the added parts. There are codes on the transistors, but I couldn't find the right google invocation to decode them. They are Motorola parts, marked, with a Moto logo followed by "616,” the next line is “JE350,” which is the variant/part number. If 616 means the 16th week of 1996 then it would make the transistors the same vintage as the rest. If it means something else though, it would be nice to know.

Given what Dave has reported from his teardowns of EDC gear, it wouldn't surprise me if the bodges are factory original, but I'd be curious if they were fitted later.

I've been keeping a eye out for a hp 34970 data aquisition unit for a while now. I've been getting cards when I see them come up cheap but still waiting for a unit to go for the right price. Yesterday I saw one appear as buy it now for AU$150 in working condition with the dmm module and it was in Australia already. I've seen parts units go for more than this so I jumped on it. I'll update here when I get it on my bench.

After fighting off the urge the urge to step up from a DMMCheck+, I succumbed when I found a deal on an EDC 521 (https://www.eevblog.com/forum/testgear/edc-521-dc-voltagecurrent-source/).

The anticipation of the 521 unlocked a new urge, the urge to have a way to check multiple points on multiple AC voltage ranges. And now, for just $29.90 + more than twice that in shipping, I will soon have 65 pounds of vintage AC calibration equipment.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=170586;image)

If I'm lucky, this compulsion ends with this 44-year-old HP 745a, and without dropping it on my foot and taking a detour to the hospital along the way.

Is it sad that I know which eBay seller you bought the Hp745a from just by the table and bushes in the back ground?

I've bought a EDC MV105G and a arbiter systems panel meter calibrator from him. Good seller, packs things extremely well and shops quickly. It's all from an estate sale, he said he has enough stock to last several months putting up new bits every week.

I figured people would recognize the seller. I know a few other members have picked things up from him.

I was surprised to realize that he's sold four HP 745a's in the last few months. I thought it was the same unit being relisted, but the serial numbers are all different. I'm a little worried I'm getting a unit the deceased used for parts. Either that, or he really liked HP AC Calibrators.

The edc unit worked although it didn't appear to have been calibrated since it was made in the 70's.

The panel meter calibrator works on most voltage ranges but the current module doesn't work.

I'm not sure what someone would do with 4 x HP 745's, but I do appreciate the collection of gear. Hopefully it works well for you.

Used Voltech PM100 Single Phase Power Analyser (the single phase version of Dave's 3-phase PM300).
As new condition, not a scratch. Received today, just got her hooked up and and it works great. I wired up a custom DUT AC outlet to the banana's on the back so it's easy to connect to.

Got it for 300 UKP via Ebay (free delivery)........there are 2 others listed, 583 UKP & 722 UKP, and new they are a helluva lot more.......so I reckon I got a bargain.

A nice addition to the w/shop.

Bummer :(.

I'm already having trouble making space for my three rack-mount instruments (HP 6332b PSU/Load, Phillips PM5192 Func Gen, and EDC 521). The HP745 is going to put me over the top. I'm sure I'll end up selling most of them, but that was kind of the plan in the first place. I'll use the EDC 521 and HP745a to help calibrate and demonstrate the Keithley 197a's I'm refurbishing and then sell the DMMs and AC calibrator off.

The EDC 521 I'll probably hold on to, at least until I stumble across a deal on something smaller with equal or better specs.  Either that, or I may try and implement a similar design using more modern components. If I do, I'll use the EDC to validate it, then find another good home for it.

I'm not sure what someone would do with 4 x HP 745's, but I do appreciate the collection of gear. Hopefully it works well for you.
If all are in working shape, I suppose its possible he used them as stable precision AC power supplies for other projects. Someone selling a Fluke 5200 recently indicated that's how they used it. With my own limited experience, I can't guess what those projects would be though.

Sounds a bit fishy to me.  I just shipped an old HP spec an, a DMM and an attenuator home from CA (I really need to stay away from the TRW swap meet!); by the time it was all boxed up it was 27 x 27 x 17" and weighed 107 lbs.  FedEx ground was quite happy to ship it, and whacked me about $90 to do so.  They arrived unscathed in about five days.

Edit to add: dropped off at a FedEx location in CA and shipped to my home (residential) address.

We had an RF equipment division of HP locally for many years. Many of my fellow Engineers worked there. When they closed it down and consolidated its operations to the Bay Area, they "let go" a bunch of test equipment including products they had manufactured there. One of my friends snagged a few things, and gave me and my techie son an HP 8921A Cell Site Test Set. Here's a photo I found:

(http://www.hs97.com/up/product/201071642143809.jpg)

1 GHz all-in-one integrated instrument: Scope, spectrum analyzer, signal generator w/ sweep, the works. Refurb'd today they cost $5K, new I think they were in the $30K range.

For free.

And it works.

We've used it a lot, especially for building and tuning amateur radio antenna traps made from coax and PVC pipe.

Value vs. cost ratio will be hard to beat!

Wow! I wish I had one.  :(

But for today, I just got this delivered - an HP 3457A DMM. Works very well, but needs the usual TLC cleanup, and removal of old gooey cal sticker goop.

Those are nice, and you got a better deal than I got on my IFR FM/AM 1000S.
I paid a hundred dollars for the IFR not working and fixed it for an additional $280.00 Lots of parts on E-Bay but they are noit cheap.

Nice score, looks to be in pretty good condition! Just make sure you change the AC inlet filter ASAP, the ones in the 3457A's are known to blow up in flames, expelling really smelly gas.

Mine shot flames 6 inches onto a freshly painted wall...and I swear I can still smell a hint of it a few months on.  :-DD

Any standard filtered one will do, just make sure you get the ones with the fast-on connectors IIRC. You can find some more details in this thread (https://www.eevblog.com/forum/testgear/just-got-3457a-and-then-boom/).

I think most of the failures was because they lived cosy lives on 100V AC, before being subject to the full wrath of 230V mains. Ah well, it's only a <$10 replacement so you might as well do it just to be on the safe side, and perhaps it's also a chance for you to replace the backup battery inside.

 I've seen that happen with hi-end vintage hi-fi stereo equipment, mostly from the 70s. One could often fine these at good prices on E-bay but as the 'hobby' got more and more exposure (they made some great equipment in that era, and not much other electronics toys to buy with discretionary money) the prices just exploded over time.

I've finally joined the Fluke 87V club, brand new for $300! Not a bad deal at all in Australia.

I also picked up a Hakko FX-100 for the same price, but it doesn't include a tip so I can't play around with it for a while. It will be interesting to see how it stacks up against the JBC, gotta see if the RF heating system is all that it's cracked up to be. :)

I took a quick peek inside the FX-100, the transformer has 220/230/240 taps, so unfortunately we won't be able to use an imported 100/110V model without a step down. Hakko are usually pretty expensive for 230V models, so that's a shame. Suncon and Nichicon caps inside, didn't have the macro lens on me so no teardown photos just yet, I will post some when I do a mini-review.

Yes, I think that awareness can increase demand, and that when demand increases and supply stays constant, average selling prices rise. This is basic market economics.

If people didn't share, it would remove a source of upward price pressure, but it would also reduce the utility of used test equipment.

$150.00 USD shipped - no pretty wood box though. If they aren't new they are very very close to it, they are mint. I have some other Agilent and Narda loads rated to 18 GHz, it's pretty easy to see the difference as I get past 3 GHz with the new load. I found some protective caps and a box with foam to keep them cozy.

Just arrived from EvilBay - HP 3561A Dynamic Signal Analyzer.  Got it for a song, listed as for parts/not working - won't power up, fuse good.  The unit appears to be in good physical shape with a near pristine front panel (the white mark near the left edge of the display in the image that appears to be a scuff is in fact a reflection from the window nearby).  Fingers crossed that it's something simple like a shorted cap somewhere loading down the power supply.  I'll hopefully get a chance to poke at it tonight.  It was built in 1985, based on the s/n.

The only thing this one falls short on is a missing pulse setting but you probably do not need that for audio testing.

Nice! I have one the same, and it is a great little generator. IMHO the only real drawback for audio use is in level settability - you will probably need an external switched attenuator such as a 355C. On the other hand, the output low is not connected to mains earth, which can be a curse in low-level audio.

My 8566AB from page 22 is now finally fixed.

Front panel got epoxied (sometimes added cotton fibers to expoxy for more strength) back into shape after removing original paint and metal coating. Added some plywood to make it more stable. Don't know why HP originally didn't do it that way.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173563)
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173565)
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173567)

Then I painted it with red steel primer paint and finally paint brushed it in black.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173569)

The PLL unlock faults were somewhat funny, because they appeared mostly at the start of a sweep. If the analyzer was set to long sweep times with narrow span, the PLL would lock and the errors mostly disappear. So I started probing around and found voltage spikes on most power rails at the beginning of each sweep. The A10A1-8 15-30MHz LF PLL would unlock or lock on a wrong frequency after each such spike. Since the YIG coils are tuned before each sweep and draw a lot of current doing so, I guessed that some of those silvery tantalum caps on PLL boards and/or YIG tuning boards were killed by ripple caused by the failed big blue 5V electrolytic cap, which I replaced previously.

Thereby I replaced most of those tantals on the YIG driver boards, A16 sweep generator board and some of those on the A10A1-8 15-30MHz LF PLL boards. As replacement I mostly used Wima PET foil caps (they last forever, but are only available up to 10-15uF and are quite large) and electrolytics (on places with less space or larger capacitance). After that, I adjusted the sweep generator pots on A16 board and the PLL unlock faults were gone.
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173571)

Finally tested it with my HP 8684B cavity tuned oscillator. Frequency wise is not very stable (no PLL lock), so I couln't test the narrower spans, because the signal would drift away.
11GHz @ -45dBm indicated on 8684B:
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173573)
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173575)

Guess that the -52dBm on 8566AB is partly due to cable losses. Maybe the YIG preselector/filter in harmonic mixer assembly is also slightly misaligned. I also don't know how accurate the 8684B amplitude really is.

Second harmonic of 10GHz/+15dBm signal from  8684B (cavity oscillators produce quite clean signal, since high Q, so you only get very small harmonics):
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=173577)

Now I need to get a Gigatronics 1026 or something similar (HP 8340/8341 is usually much too expensive for me) along with power meter to verify the amplitude on all ranges.

OK, that unit is only ten years younger than me, and somebody has removed the mains lead (possibly even for a good reason). However for £30 I still think it is a nice score  8) . I am planning to restore it and use it in my lab.

Yay. My time to score some test gear plus some other stuff.

The test gear is chinese but was practically free, so i couldn’t say no. And it is all new.

The test gear is from a friends dad, and to makea long story short they are now mine to sell, and the clamp meter and multimeter are mine to keep.

I took the clamp meter and the multimeter apart.
The clamp meter has solid input jacks, and a really good continuity buzzer, good range of funktions, and metal threaded insert for the battery door.. I’m impressed.
The multimeter is just a cheap multimeter with an unfused 10 A range. Nothing to write home about.

Other than the clamp and multimeter there was a  Victor 824 sound level meter, Victor 816B anemometer, VC60B megger, Victor 1010A lux meter, and a CVS borescope. All the finest test gear chinese yen can buy.

Wait. There’s more than test gear.
I scored 6 racks mostly full of components, some test leads, and some random stuff for 3 cases of beer.
This lot came from a colleague, whoose former profession was EE related.

I've included pictures of the above mentioned gear.

I also scored some power tools incredibly cheap.
New Dewalt dcd734 14,4V drill set. comes with two li-ion batteries and charger.
Used Bosch phg500-2 hot air gun
Used Bosch pbh16re  sts hammer drill
Used Bosch gst500pe jigsaw
Used No name drill
All in great shape.
If you want i will take some pictures of those too.

Did one of your manage to snag the HP 3458a that sold on Thursday for $2K less than an hour after it was listed, because I didn't (thank god, I think, maybe).

Much more mundane, but I did manage to scoop up a 34401a for just about $200, shipped. It arrived today. The most obvious defect in the listing is that the front/rear terminal switch wasn't quite right. Turned out the button/extender it had just pulled free of the locking notch on the switch. I fixed it by mistake while putting the meter face down to open it. It's also missing a handle, as expected. Display may be a little dim, but quite readable.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=174154;image)

Passes the self-test. Looks like it was made in the early 90s. There is a cal sticker dated from ~5 years ago. Checks against my DMMCheck+ are consistent with a properly functioning meter within it's tolerances on everything I can check, except the 100Ohm, which is range is a bit further out. Now to decide whether to keep it as one of my working meters, replacing a Keithley 2000, or sell it. Diversity of manufacturers is appealing, but one of the reasons I bought Keithleys in the first place were the slots for a MUX/switch card.

but I did manage to scoop up a 34401a for just about $200, shipped

Good "score" eas! They've been going for quite a pretty penny recently.

Display may be a little dim, but quite readable.

Looks OK to me, especially considering its age. I've seen worse.

Passes the self-test. Looks like it was made in the early 90s.

Looks similar vintage as mine. Does the serial number start with 61?

Now to decide whether to keep it as one of my working meters, replacing a Keithley 2000, or sell it. Diversity of manufacturers is appealing, but one of the reasons I bought Keithleys in the first place were the slots for a MUX/switch card.

Well, given the prices they're going for right now, selling it is a rather tempting proposition.

Earlier this year they were cleaning at work and I scored a HP5335A counter, a 30V/10A Oltronix PSU and three HP 3456A digital voltmeters for free. Later I built my own RF prescaler board for the counter, it works ok but a lot of room for improvement wrt. sensitivity.

Last week I found a Fluke 6060B RF signal generator for $210, cheapest one I can find right now is $650. Downside was rear mounted connectors and no guarantee it was working (though "pulled from a working environment").

Got it yesterday, works perfectly, despite having a fan there was hardly a trace of dust inside. The Cal sticker on the outer panel was broken, presumably when the original owner pulled the GPIB module, but the inner electronics can still had an unbroken sticker.

The connectors were trivial to move back to the front, just had to shorten the modulation cable, remove the original semi-rigid SMA-SMA assembly and N-SMA connector and replace it with a new SMA-N adapter (original wouldn't fit with the screws on the front) and a small SMA-SMA patch cable.

The up-arrow button is slightly less sensitive than the others, and the membrane is partly ripped on the RF on/off button, display works, RF output is perfect. Original timebase is the standard type, pretty close to spot on all things considered.
Already ordered parts to mount an OCXO with a separate always on PSU just for kicks, but for now it's connected to my GPSDO along with the rest of the gear.
When I install the OCXO I'll try to fix the membrane and clean the arrow key.

Just recently, another Fluke 87V for $25. (no leads, rubber boot or case, and for that price, don't care).

This weekend at the local swap meet, a Fluke i410 AC/DC 400 amp current clamp for $10.

It is not a recent score, but still a nice one! I am considering an LCD display replacement from simmconlabs.com, perhaps if I will use the 3563A more often such an investment would make sense.

Cheers

Not really test equipment, but I just picked up a 90's paper tape reader/punch for $30.   These still go for several hundred bucks on ebay when they show up (there's limited application for old CNC equipment).  A roll of paper tape costs more than that these days.  Only problem was 4 rotted grommets holding a drive motor.  It reads at a blazingly fast 400 chars/sec ; that's a high-speed reader :-DD

One paper tape char = 6bits = 0.75bytes? Which would make an amazing 300bytes/s or 1.08MB/h.

BTW, what is the capacity of paper tape in kB/tape? Just wondering, since that is the last human readable form of digital data storage.

I recall having to fly to Renton WA in the 70s. to service/commission a mini-computer system for Boeing aircraft. The system generated  mylar punched tapes used for all the CNC equipment for the aircraft being built in that factory, 747s I think. It was a hugh building that had building inside of the building!

I also serviced teletype equipment in the US Air Force, they used the old 5-level paper tape. So lots of tape chad passed over and around this old fart.   :-+

The electro-mechanical Creed teleprinter/reader combos I used to use when I first programmed computers where five hole 50bps on an 80V 20mA loop. The optical readers on the computer itself were much faster, 500cps, or 2,500bps with 5 hole. For me they were a marvel at the time, but the teleprinter mechanicals were well beyond me, I'm definitely an electronics dude.

Edit: for really trivial typos, you could fix the tape manually by punching holes yourself or filling them in, and hoping the hacked tape didn't get stuck in the high speed reader, because if it did you had a splicing job on your hands too.

Here's my score and it was free! A fully optioned Tek 2465 DMS Scope. My brother works for a device placement company that was going to write it off and scrap it. He asked if he could have it and they agreed and he in turn gave it to me. It's mostly functional with a few issues that I've been working thru with the help of the Tek Yahoo group. I plan on joining the 2465B teardown thread where I'll go into detail as to what's been done so far and what is left to do.

my work is clearing our pile of dead and obsolete junk from our "graveyard",
Generally nothing interesting, but I've saved a handful of cherrys from the lot.
I've got a tektronics scope ( i think its a 465 from memory)
A huntron tracker
(http://i.imgur.com/rw3tGqpl.jpg)

a couple of tektronics TM500 ( i think) racks.
(http://i.imgur.com/hyeAM3ul.jpg)
in the smaller rack there are:
dm502 Digital Multimeter
DC 501 110Mhz counter
SG502 Oscillator

and the larger rack:
DC504 Counter/timer
FG504 40mhz Function generator
FG502 Function generator

most units seem to power up, the only unit that doesn't seem to work is the FG502 function generator. there is no on light, so i can only assume for now that it doesn't work



a dynascan 520Mhz frequency counter
(http://i.imgur.com/1HUXg6Il.jpg)

and some other bits and pieces, mostly probes and leads.

There is only a couple of other bits of any vague interest left to go when the garbage people come back, but I figure they are of little use, to me anyway, like colour TV pattern generators, a tektronix 305 data analyser, and a beefy looking Trio AC volt meter, so the tip will get those i guess.

Now I think i have got some neat old gear. Overkill for my experience, but hopefully they will come in handy some time!

You sure about that tek 305?  A Sony/Tek 305 was a 5 Mhz scope with a builtin dmm.  If that's a 308, grab it.  The 308 is an 8 bit LA that also does signature analysis and rs232 decode.  It's not a great LA, but it's nice for small projects.  The signature analysis is good for Tek and HP equipment up to the early 90s if the service manual has signatures.

You're right, I miss typed, Its a 308 data analyser.
Crappy pic:

I didn't bother with it because when i previously investigated it, it sounded like it had a fairly specific purpose.
I figured it would be more a waste of space in my shed as much as anything, but if it can do things like RS232 decoding, that might make it handy to have all by itself, heck, that might make it useful for me at work.

Aargee:
unfortunately its not really possible to offer the majority what is there.
If someone had a use for the video signal generators or something, I could probably manage that, but that's about it i'm afraid.

Just picked up an Agilent 33120A AWG with the external ref in/out option for a great deal off the 'bay. Yes it is older but it has wonderful specs in the audio region and I just couldn't pull the trigger on a lower end Rigol/Siglent.

33120A arrived the other day - turned it on and ran the full self test which is promptly failed. So while it was a good deal perhaps there was a reason! Contacted the seller and he refunded part of the sale price after some negotiation. So now it is a repair project. The unit itself it actually in very good condition and still had the Agilent factory seals in place. It fails with error 603 and 608. 603 is a ram test failure - the ram is in stock @ Digikey though, will get it next week. Fingers crossed error 608 will go away once 603 is fixed.

I had a chance to compare them against the new one with several voltages and resistances and they were dead on.  They're also dead on relative to my HP 3478A.  I'm very happy!

Very nice price.
We use to have one of those on the production floor at Loral.
Everyone had analogue meters, whenever we had a transmitter that was margional on power it was time to go grab the GOD BOX (HP 436 with the high poiwer sensor) and see how marginal said transmitter really was in terms of power out.

Yes, its in astonishingly good condition, the sensor doesn't have a mark on it, neither does the meter. Its as if it was bought for some project and never used.

Usually 2nd hand sensors are scuffed from all the use, but not this one. And the meter has no use marks from having its buttons pushed. You usually get a shiny halo around a button after years of use, but not this one.

I haven't opened the meter yet to check inside, but I will soon :)

I've tested it up to 3Ghz so far and its spot on too.  :-+

eBay has served as a critical springboard for my businesses transition into electronics. "Scores" are not just fun, but they give someone like me access to capabilities that would otherwise be out of my reach financially.

I design power electronics. Multi-channel, multi-voltage, in/out monitoring, etc. What was needed was a way to test the rather complicated PCB's after they are built. I found an awesome Keithley 2700 which is a typical high-performance 6.5 digit DMM but with to option ports in the back. I added a 20 channel multplexer to it so that I can automate 20 measurements with LabView controlling it. Amazing little box. I can even add another card for a total of 42 input channels. Each channel can be R, I, or V.

(https://solidcamera.box.com/shared/static/hlbl3d1hxqnd2mtny8fxo2di2aejy6ng.jpg)


Next up is the Chroma 8 channel DC electronic load. This is a beauty for me. My power designs are setup to supply many loads that have very different characteristics. Connecting this to LabView, I can simulate all kinds of terrible scenarios as part of the design validation. For production, it allows me to connect every output of my system and do automated load tests. These units can be rather high-speed and simulate inrush currents. Not quite as fancy as the newest models, but FAR less money - like 95% less than new.

Swapped out U404 and U405 and the 33120A is working perfectly. It was another 15 dollars for the new ram including shipping, not too bad at all. The 33120A is in great shape with the ref in/out, bumpers and handle.

I scored a Keysight branded 33210A function generator for a little over Euro 300.
This one is brand new, was listed as probably defect, showed only a bad picture in the listing.

Just unpacked it and it works perfectly and looks as if it is brand new.
List price in Germany is almost Euro 1400 incl. VAT


Only one problem: It does not have a serial number sticker at the back, so I can probably not send it out for calibration. Hmmm.
So, once in a while there are good deals around.

@HighVoltage does the Utility menu give you the serial number?

No, the utility menu was not helpful. But the I/O library was...

Just hooking it up to Keysight Connection Expert, reveals the serial number without any effort
It is listed as Serial Number SG48000515
It was originally calibrated on 2/11/2015
And warranty was activated on 7/20/2015 and is good to 2/4/2018
The calibration certificate can be downloaded from the keysight website

So, why would someone list this as "defect' and is willing to let it go for such a low price.
And why is the serial number sticker missing?

Stolen equipment ?
Hmm, that thought has crossed my mind.
Not a good thought.
But how to find out, if I even want to find out?

It is a good thing to worry, yes.
Because, if you bought a stolen equipment, you are helping the criminals, helping this kind of thing happening.
Imagine a scenario, if no one would bought a stolen piece, for what I will stolen (only If I could make some use)...

But on other hand, it is really hard to know if the deal is right or not.

Here in my country it is very common get your stuff stolen. And if the cops knock your door, you may (MAY) go to the jail, if the price is so incompatible to the market, that you could imagine that is illegal.
In some cases like that, I like to ask to the seller some questions about the item and technical things too. Something like:
'Why are you selling this', or in this particular case, 'This genereator can make a sweep on senoidal waveform'.... somethings like that.

But now, as you already bought, let this tought alone... ;)

The police must have proof that it’s stolen before they knock at your door. They also have more serious things to do.

Nice buy.  :-+  If you are worried, sell it to me.

No, I am not worried, I am happy to have it.
To the contrary, if they come and knock it will be something new.
I will be using this generator mainly for pulse applications and it works very well, down do 40 ns
Not comparable to the newer 33522A models but more than good enough for most pulse applications in the us range.

Thanks to stiffman (https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here (https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here)!/msg774280/#msg774280 ) for $15 postage, these:
* Philips PM 5519 Colour TV (PAL) pattern generator
* Black star 1410 video monitor tester

The PM 5519 works fine, see pics.
The 1410 I don't know yet, may need a manual. It seems to be outputting standard PAL video freq signals on PC VGA style connectors. So the LCD monitor I tried just says 'out of range'. But there are setups on the back panel, that change things.

Many people would consider PAL video gear obsolete. But I have some PAL composite cameras and monitors and other stuff, that serve perfectly in a long term project. Nice to have a good test pattern generator. I have one already but it isn't so good.

I am not worried that the police will knock on my door and that a good score turns in to a nightmare.
And I don't think there is a way that I could get punished in Germany for buying something that could have been stolen.
Not trying to de-rail this thread, but in Germany, buying stolen goods ("Hehlerei") will be roughly be punished as hard as stealing the good. (It sounds excessive, but that's the historical goal). However, there needs to be proof that you knew about the fact that it was stolen; a price that's off by an order of magnitude is considered to be a strong indicator.

That said, while you got a very good deal, it's not not totally uncommon on eBay. I wouldn't be too concerned in this case, especially since you posted the serial number (so if the device should end up stolen, the owner can talk to you and resolve the issue), but it's a good thing to keep in mind.

HP 8714C .3 MHz - 3 GHz network analyzer advertised as not powering on and sold for parts. Received it today, it didn't turn on as expected. Checked the power supply diag LEDs on the back, the HP troubleshooting guide suggested to check the 115/230 volt selector switch based on the lights. I flipped it back and forth a few times and tried again - it now boots fine. Fingers crossed that is all it was and that it keeps working. It needs a good cleaning and I plan to try "enabling" a few options. The green screen is still plenty bright and isn't burnt in, and unlike the higher end units from the same time period this unit has VGA out - color even. What a fantastic toy to have on the bench. Connected is an HP 3db attenuator and a length of coax cable - it all looks good.

edit - best $500.00 I have spent in a long time.

Added a pic checking out a "home made" precision 50 ohm SMA load I've been using with my spectrum analyzer - looks not too bad at all.

Big thanks (or was it bitter bitter remonstrations?) to Dave for sharing the UK NVIDIA auction. I now have an R&S SMIQ 03B with OCXO, data generator, modulation coder, and arbitrary waveform generator. Also pinched a "Kewithley" 427 Current Amplifier and Perkens Elmer (now Signal Recovery) 5184 voltage preamplifier.

With pickup, tax, and auction cut I should probably be remorseful, but it's my birthday tomorrow...  ::) So that's a pretty good excuse!

DMM Mastech MS8260 - Free from DealExtreme, using some points and gift card.

A Keysight DSO1072B (2 ch, 70Mhz oscilloscope): US$ 260, from Farnel Newark. Not exactly a steal, but they are often sold for over US$ 800. Since Farnel Newark is closing its operations in Brazil, they're having a huge clearance sale. That's also how I got a Fluke 17B+ and a 117.

OTOH, I've given away computers, printers, monitors (CRT and LCD), Arduino boards...

A co-worker of mine just scored a Matsusada RK series benchtop supply from the scrap bin.  Another subsidiary of our parent company in our building tossed it.  Turns out the only thing wrong was that some idiot set the config on it to limit to below 1V...  A quick parameter reset using a PC and he now has an awesome bench supply.  I managed to score 3 Agilent turbomolecular vac pumps that still spin freely so who knows what is "wrong" with those!

I've been looking for a turbomolecular pump (that works, ie with controller, that I can afford) for sooooo long. You lucky bastard.

Invariably the turbo pumps on ebay are without controller. The same seller may or may not also be selling some controllers, that may or may not be compatible or broken. All at stupid prices, How many of these things ever sell?
It seems incredibly stupid for sellers to separate the two parts, which are completely useless independently.

They were in the "scrap" bin but they are perfectly clean (class 2 ISO clean room IIRC) with freely spinning rotors.  ONE has the controller.  I don't have any way to test them, really, since spinning them up (if the controller even works) in atmosphere would end badly :)  I have no use for them and grabbed them because A) cool as hell and B) I have a "problem" lol.  I have a lot of industrial parts in boxes and getting rid of stuff will make the wife happy :)  I will have to post what I have in the classifieds.  Intrinsically safe barrier modules (ATEX),ATEX 3-phase stainless food grade pumps (used for PURE IPA pumping), Turck parts, WAGO parts, Omron PLCs, VFDs, Galil motion controllers, sensors, etc.  When the company moved they scrapped all kinds of equipment.  I missed my chance to grab some pure copper "targets" from our PVD tools, unfortunately...they were 80lbs each.  But I do have some Gold test wafers which are cool:)  Every now and again I see a 2 or 10KV power supply in there so if anyone wanted one I would gladly grab it and ask postage.  I never grabbed one since I have to draw the line somewhere before I end up on Hoarders...

Hey, post some of that stuff in market place here. Doesn't cost you anything and I guess quite a few guys here would be happy to get cheap/free HV-PSU. Including me, if it's a nice one and shipping isn't too much.

Would have also grabbed those turbo pumps. If you want to test them, you have to close the big end and attach a rotary vane pump on the bottom flange of the pump. Since you probably don't have big flanges to shut the big end, you can also bolt two pumps together and seal the small port of second pump with small flange. Then evacuate the pump and start the controller and see whether the pump runs smoothly.

If it does so, you can list it on ebay as working replacement. Since those pumps occasionally crash, and OEM replacements cost $$$$, you can sometimes get quite good money from them, especially if someone needs replacement quickly.

Hmm... should I take that as saying you're prepared to sell them to me cheaply? I have a US re-shipper account, so you'd only have to post them to CA USA. But pack for international shipping. I can advise if needed.
Are the three pumps all the same? And the controller has the cable to the pump, and the plug fits?
What are the model numbers? If you're interested in selling, can you show pictures?
If they are all the same, or different but the controller is compatible with more than one, I'd like to get them all. Better chance of getting one working, and also having spares is good.


I have a project I've been working towards for years, part of which is a large vacuum chamber. I'm at the stage where I have to decide whether I'm going to give up on ever finding an affordable turbo pump, and just go with the big oil diffusion pump I have. I'd rather not, since oil diffusion pumps seem like they are a major pain in the butt. Backstreaming, oil everywhere, potential for oil mist explosion, cleaning, nasty oils, power hungry, lots of heat in the room, water cooling needs, slow cycle time, etc.

There are some peripheral bits of the project online:

  http://everist.org/NobLog/20141212_racked_serendipity.htm (http://everist.org/NobLog/20141212_racked_serendipity.htm)
But overall I don't talk about the intended purpose, so sorry, no point asking. It's a very worthy cause though.

The chief problem is, I'm very poor. Retired, extremely tiny income. So if you want market rates for them, I probably can't afford.

You don't happen to also have any vacuum sensors and their controllers? Especially of the cold cathode type (not so easily destroyed by vacuum mishaps.)

RACAL-DANA 9514 (9500 series) Universal Time/100MHz Frequency Counter with options:

Option 22A
Quote
Aging Rate: < 3x10-9/day*
Temperature Stability: < 3x10-9/oC 0oC to +50oC
Voltage stability: < 2x10-8 with 10% line V variation

*After 3 months operation (I believe it worked longer than 3 months :] )

Option 70 - Analog Trigger Output
Quote
1.4.7.1 This option provides a DC voltage available at the rear panel which corresponds to the triggering level of the input. It has a range of - 3.2 V to + 3.2 V. It will mirror either the analog setting, or DAC setting (on 9512,9514, or 9515 only) depending on which type of trigger level selection is in control. The output trigger level is independent of the input attenuators, for example, if the trigger level output reads 1.5 V and the X100 attenuator is in use, the internal trigger level is (1.5 x 100) V or 150 V.

Last calibrated: 11/10/2012

Price: 75 USD

The only problem I have with it is laud fan. Looking for nice replacement.

At ~$300 shipped, the physically damaged Datron 1081 7.5 Digit DMM (https://www.eevblog.com/forum/testgear/datron-1081-manuals/msg780705/#msg780705) I received about a week ago probably is less a score to be admired than an object lesson in the dangers of volt-nuttery, but its still pretty cool. I'm still puzzling over why I felt pretty good passing up a few chances to get a working Keithley 2001 for ~$500 while diving headlong into buying this thing.

(http://d112tss1dzpest.cloudfront.net/wp-content/blogs.dir/22/files/2015/11/IMG_9164-e1446410672551-1024x768.jpg?323d81)

Maybe it's the 2cm high digits on the neon VFD display? Or the repair-friendly through-hole construction?

In any case, it seems to be working pretty well on DCV, within the limits of the meters and references I have for comparison. I need to make up some new kelvin leads to check the resistance function. Not sure what to do about ACV. There have been a few issues which may be user error, software bugs, or as yet undiagnosed hardware issues.

Bought a broken Agilent 34450A multimeter off of ebay for 150 dollars. It had something loose inside according to the listing. Turned out there is a service note regarding this meter - the metal shields have been known to fall off or come loose on some units. The unit was still under warranty so I sent it in and received a brand new Keysight branded 34450A this morning. It was calibrated yesterday. Another great additional to the bench and the reason why I will continue to purchase mainly HP/Agilent/Keysight products - they are so well supported and generally have been for the history of the company.

Don't get me wrong, i love those displays. Got these two just because of the looks.

(http://members.home.nl/baltusg/DP3500.jpg)

The displays have much better looks than this photo. LED, nixie or VFD don't even get close.  8)

As meters they are ok. Replaced leaking caps and did a quick "calibration" agains my reference. But i'm not using them much for measurements. The auto ranging is sloooooow. And i had to replace a display on one of them. Took me two tries to buy a piece of second hand equipement to get a good one. Think very old industry panel meters (e.g. analog devices).

The displays do look nice. I think OLED is even better for contrast and such but I fear for the overall lifetime of the display. I don't think the display on my 34450A will last 20 or 30 years, never mind 40 or 50.

I've been hitting ebay hard lately, wife is about to kill me. This should be the last goodie for a while.

Made a low ball offer on an HP 53132A universal counter with option 010. The ad had the first picture of the counter upside down and it wasn't powered on in any of the pictures. The seller did state it was power on tested only - so it was a bit of a gamble. The listed price was $814.99. I offered $400 - they countered rather quickly at $600. So I countered at $425 shipped and said I didn't know if it really worked or how bright/dim the display was as it is an older HP branded unit and that was the most I could offer - 5 minutes later the seller accepted!
Received it today and it was actually very clean overall. The display is also very bright, it can't have been powered on too many hours. I verified it worked perfect and was super pleased at this point. Then I figured I would update the firmware. Well this is a rather dumb move if you don't save the calibration values before hand, and of course I didn't. The firmware is held in 4 29F010 PLCC 32 flash chips and is probably not really intended to be user upgraded. I had found newer firmware for download on the internet. I am a sucker for newer firmware, always have been, bricked a few devices because of it over the years. It seems I still haven't learned my lesson. It powered up with an EEPROM error, then the next power up it seemed fine. However every power up after that it now said it was "UNCALIBRATED" - opps!   Now thankfully the story has a happy ending as I have happen to have the gear needed for a basic calibration(it doesn't need much) and it is working great again. Whew - so lesson learned I suppose.

I troll ebay quite often throughout the work day and most evenings, mainly for HP/Agilent/Keysight gear. I've seen tons of buy it now items that are smoking great deals. Often it isn't gear I need though or already have etc. I think maybe another thread should be started with hot deals, when someone sees a great deal and they aren't buying it themselves a link could be posted. I know I'd rather see someone from the EEVBLOG get a great deal vs a random person.
One last thought - I really feel for anyone not in the US trying to get the insanely good deals. I am in Canada but have a US shipping address and it is only a few minutes to cross the border to pickup packages. I can bid on most US based auctions but not all so I still feel pretty lucky.

Well, that is not entirely true.
Although, I must say that the quantity of Agilent / Keysight items on ebay USA is much larger than anywhere else, but the prices are lower in Europe and sometimes I have gotten deals on ebay Germany or ebay France or ebay Italy that I can not even believe myself.

I just got an Agilent 34901A 20-Channel-Multiplexer Modul for less than 5 Euros.
And it is in perfect - like new - condition.

The great deals are out there, we just have to keep looking.

this Keithley 192 cleaned up nicely

I have also been having good success with lowball eBay bids.

The 192 and the 175 above it were purchased for $38 + $18 USD.

After removing sticker residue and case cleaning, the 192 required retigthening of the mains transformer mounting studs and the 175 needed the REL pushbutton switch cleaned.

Both have spot on calibrations with cal stickers from 2008 and 2012.

That is true. I found a seller on ebay.ca that never seems to sell anything and at times he heavily discounts items. Turns out all items are only able to be seen from ebay.ca, so his viewing audience is quite small.

I need to clean up my equipment and make better photos. Sorry. Most of the stuff is from the broadcom auctions, but the HP 34401A was from ebay.

But nevertheless:


Got a bunch of other stuff as well from the auctions, but this is the most useful stuff. I'm particularly happy about the PCIe tools; they were pretty awesome bargains, and hard to obtain used. They are also very new (2013/2014). The Z3-16 is still the top-of-the-line exerciser, and the T24 is their lowcost analyzer (which does everything I need - 4x Gen2). I need to build a iPass PCIe probe, either passive or active. For the Z3-16 I also need to build a host emulator setup - I hope I can just wire together two PCIe slots.

The MD8480C is nice because it allows me to connect any GSM/WCDMA equipment to a local network. For GSM compliance testing (which I was trying to do with OsmocomBB), the CRTU-RU is much better (since it comes with the 3GPP test case implementations), but for a simple "let's see how this wireless device talks to the network", the Anritsu is nice. Unfortunately I only have the very basic software for it (i.e. no test cases, no network-in-a-box), but since it's all delivered in source form, it's "just a matter of writing some code".

About 47 years ago when I was in grade 12 electronics class at Ottawa Tech HS, we had some 3 broken Heathkit OS-12 scopes and the teacher asked for volunteers to fix them if possible.  I said I would get one working provided I get the carcasses from the other two used for parts.  I did it and when I got them home I found that one needed only a new fuse.  I've been sworn to secrecy from then on since I was told that heads would roll if the deal was found out.

Not as good of a score as a lot of you guys / gals pick up, but I just got a Chroma 6512 AC power source, 0-300VRMS 0-20A 15-2000Hz(Max power 1200w) for less than $1000 AU delivered (Shipping was a fair chunk of that).

The unit arrived yesterday with a fairly nasty rattle, I popped the covers and found the main output stage had shifted. They go to a lot of effort to isolate the heatsink from everything else electrically, and this was hitting the next heatsink. I removed all the screws (There were a lot missing and they were rattling around in the case), took it out, refitted the brackets, re-mounted it before checking as much of the visible boards as I could. The input fuses were in tact, there were no blow marks or anything visible. This is the reason why you shouldn't turn it on, but take it apart. If I turned it on first, there would have been a heck of a lot of damage done, possibly rendering the unit useless.

Anyway, turned it on and after a few clunks of the relay and a very neat POST beep tune, it sprung into life. A few checks with meters and the scope and it is a few hundred mV out at 240V (Or my meter is, who knows). I have done some load testing this morning and it is working. Just need to get used to where stuff is in the menus and find out where I am going to fit this monstrosity on the bench (Seriously, it is 425mm x 225 x 575mm and weighs a lot). The only issues I see so far are the missing encoder knob and the display has horrible viewing angles (More of a display issue than the unit being faulty)

I'll try to get some photos and post them up.

I managed to score 3 Agilent turbomolecular vac pumps that still spin freely so who knows what is "wrong" with those!

With or without controller units?
I've been looking for a turbomolecular pump (that works, ie with controller, that I can afford) for sooooo long. You lucky bastard.

Invariably the turbo pumps on ebay are without controller. The same seller may or may not also be selling some controllers, that may or may not be compatible or broken. All at stupid prices, How many of these things ever sell?
It seems incredibly stupid for sellers to separate the two parts, which are completely useless independently.

If one accepts the task of building a driver for the motor (probably a BLDC driver in most cases), then you would be able to bid on a lot of pumps that the majority of potential buyers will ignore because of the missing controller. There are a couple of people on youtube who have done it.

Maybe. It's the kind of 'one off, open-ended, unknown unknowns' guaranteed lengthy design challenge that I prefer to avoid though. Other problems are that many turbo pumps have magnetic suspension, and involve a lot more than just spinning up a rotor via 3-phase AC drive. Besides, even lacking their controllers, virtually all the turbo pumps I see on ebay *still* cost more than I can afford. Especially for something that is in unknown condition, and probably there will be no identical unit available as replacement if something goes wrong with it. I have no idea why the prices for potential junk are so high. Is there really a market for used turbos, or do sellers all just assume there must be because new ones are so astronomically priced? Any time I watch a turbomolecular pump on ebay out of curiosity, they never sell. Has anyone here ever seen one sell?

This hunt is a never-ending frustration and torment. Now the guy with those 3 turbo pumps casually mentions that "He'd like to try spinning the one with a controller up, to see how it goes." He means, in room air. Oh God. I feel like screaming "NNNnnnnooooo!" but must stay calm and polite. He's not familiar at all with vacuum technology, has no idea about contamination, realistic pumping volumes, avoiding fingerprints on HVac surfaces, etc. Keeps taking the end caps off. Makes me want to cry.

Edit: Even complete wrecks of turbo pumps still list at stupid prices.  Have a look at ebay 141680021356
An Agilent TV 301 that's had a severe blade crash. Spectacularly mangled, but still listed at $150. Oh wait I'm sorry, $149.99.

Long ago I worked in a particle accelerator lab and we used a TM pump on the main beam line.  Whenever we had to pump down the line from atmosphere I'd grit my teeth until it came up to speed.  Can't imagine what it would look like inside if it crashed.

Beats the heck out of a diffusion pump; be kind of fun to have one in a small setup.  I rescued the vac system out of an EM at my local scrap yard, so I've had a 6 inch diffusion pump sitting on the shelf along with a backing pump.  I go back and forth about putting it back together and getting rid of it.

Turbo pumps might be more robust than a lot of you seem to give them them credit for being. Way back when I worked for National Semiconductor, we had one sputterer (a Perkin Elmer unit, IIRC) that had a turbo pump.  The sputterers that I worked on had cryo pumps, and most of the other hivac equipment had diff pumps.  I never worked on the P&E sputterer, so the extent of my knowledge of the turbo pump at the time was that it was a mysterious thing that spun insanely fast, and that like the cryo and diff pumps, once it was up to speed and vacuum you gated it off and left it running unless absolutely necessary.

A year later, after that National plant closed, I started working for a small company that made electron microscopy sample prep equipment - small table top coaters, and freeze fracture/freeze etch machines among others, all of which were high vacuum.  Many used turbo pumps.  Few if any had gate valves for them - they were bolted directly to the chamber and started/stopped as the unit was pumped down or vented.  I nearly had a heart attack the first time I vented up the small tabletop coater when I heard the hiss and the shriek of the turbo as it was powered down and immediately vented to atmosphere!

It soon became routine, and nothing to even be concerned about.  The systems roughed through the turbo as it spooled up, and vented it as they shut down.  Granted these were not HUGE turbo pumps (330 and 510 l/s ones being the largest I recall), but they seemed unfazed by this treatment and seemed to live fairly long lives before needing rebuilds, and those were typically for bearings and certainly not crashes.  I can't recall seeing a crashed one in the 4-5 years I was there.

They certainly proved to be tougher than I had initially thought, given the tight clearances and 30-50,000+ RPM speeds they operated at.  (The smallest, a TPH 060, spun at something like 90k RPM!)

For what it's worth.

As I have to deal with high vacuum systems on a daily basis and these things contain turbomolecular pumps, I've asked one of our engineers about the details of how fragile these are. And the answer is: not that fragile if you know what to avoid, like tilting the pump at full speed of venting it hard to the atmosphere. Apparently it is a good idea to mount the pump with not just a working condition in mind but a catastrophic failure condition too, as a pump rotating at full speed can do quite a bit of collateral damage if not secured well (I've been told a story how a large turbo went through a brick wall when the bearings failed). You can even start the pump in open air just to see if it rotates well, just not to let it speed up (and as these things take minutes to reach full speed even in vacuum you have plenty of time to switch it off).

Cheers

Alex

Nice haul, highlux. Lots of older gear there, but there are some useful pieces especially for a audio/amplifier guy. The distortion analyzer sticks out. The variac will be useful, and you must have at least one or two good signal generators. The curve tracer may be good for matching transistors for amps, either to get a good matched long-tailed pair for input stages, or for matching other transistors between channels. A pulse generator with fast rise time is a good thing to have to calibrate an oscilloscope's mid and high frequency response, and is good to check that an amplifier is stable and does not exhibit ringing with a step input. The Genrad 2220 Bug Hound may prove useful if you can familiarize yourself with how it works and how to use it to trace faults.

Yesterday I stopped by a surplus store and scored a nice working Tek 2465A 350 MHz 4-channel analog scope for CAD$150 (~USD$110 ), and a Xantrex 6030D (XT 30-2) dual 30V/2A power supply with GPIB for CAD$75 (~USD$55).  I also picked up a 1/2 lb spool of 0.010" 63/37 solder for $5. It's a little thin, I wanted 0.015 or 0.020 but you can't argue with the price.

I certainly didn't need another power supply, as I have far too many already, but I did really want one with GPIB so I could do some automation of battery charging and other tasks. Both work great but need some cleanup. The power supply front panel is horribly yellowed; I will break out my homemade retrobright mixture and UV lamp and see what I can do. I haven't yet tested the GPIB. The GPIB connectors look shiny new and the address dip switches are both set to zero, which indicates to me that the GPIB has never been used.

The Tek 2465A is an example of one of the last and best pure analog CRO scopes. The front panel controls are push buttons and rotary encoders instead of old school clunky switches that the signals actually travel through. It has on-screen readout of parameters (vertical and horizontal settings, cursor measurements, etc). Two strikes against this particular one: no GPIB option, and it's not a 2465B (400 MHz). It quite good aesthetically, but it has some very stubborn permanent marker on the plastics  >:( and one missing control (horizontal vernier), but it is otherwise in very good shape - no dents or cracks. The CRT is OK but not razor sharp, and it could use a contrast filter. I don't know if I will bother with trying to sharpen it. I know some here turn up their noses at analog CROs but I am thrilled to add this one to my bench at a bargain price.

How did I do?

Made out like a bandit. There are multiple units there that each one was good value for $600.
One thing you didn't mention - did he have manuals for any of that, and did you get them? Hopefully.

I've just had a nice score. Not test equipment, but still...

On Thursday I spent the day cleaning and polishing furniture, at my mum's place. She's too old to manage such things now.
On the way there I'd seen a kerbside toss 'office machine'. I've been trying to resist picking up junk since I really don't need any more stepper motors and metal rods, etc. But this was a big, quite new looking thing. I didn't even pay attention to what it was due to being in a hurry. I've been hoping to start finding digital copiers containing hard disks and thought this might be one. So far none (too recent I guess.)
When I got it home and looked, it turned out to be a color laser printer. A Fuji-Xerox Docuprint C3300 DX. It had been out in overnight rain, so had water through some areas inside. Thinking it would be interesting to tear down a color laser printer (never had one before) I left the covers open for a while to dry it out. (Hot here in Sydney atm.)

What started to get my attention was that it became clear the unit had been owned by someone either very heavy handed, or bad tempered. A few physical breakages, all obviously from user slamming body doors open and closed violently, wrenching paper guides, etc. The obvious ones:
 - One hinge on the main front lid. Pin popped out of position, so there is no actual hinge. Halts the machine since the door doesn't position properly and it carries the main paper feed path. Pin easily popped back into place.
 - Restraining arm and damper on left of main door, snapped right off. Also prevents the door closing unless you carefully steer the broken end while closing the door. I think the other half is inside the case. If so I can repair it. But not critical.
 - Plastic gear that equalizes the manual paper feed guides. Had popped off it's pivot and rattling around loose inside. Just popped it back on.
 - A thin plastic guide that's part of the manual feed path. Obviously broken by violently opening the front cover. Fixable.

I thought hmmm... angry idiot owner broke the machine. I wonder if that's all that's wrong with it, or was he angry due to some prior fault? Looked at toner cartridge prices - no way I can afford to buy new cartridges if they are low.

The plan had been to immediately dismantle it, not even bother powering on. But what the heck... it looks in good condition otherwise. Just in case those are the only things wrong... I waited a couple of days till it was well dried out  then after fixing the critical hinge pin, powered it up.

Ha ha... it works. At least it prints a clean B&W page of status and settings.
So funny to see the page counters:
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=186799;image)
Meaning, the color cartridges are full. I wonder who bought a very expensive color laser printer, then only used it for bulk B&W printing?
Now to get the manual and drivers and try color printing.
I don't really care if it works; it's not like I greatly need a color printer. But amusing to get a good one for free, and with full color cartridges.

Ha ha ha! I just realized. In restoring an electric motor for a vacuum pump, I'd made a note to print off a little replacement label for the wiring details inside a cover. The original had to be scraped off prior to repainting.
See http://everist.org/NobLog/20151112_planning_vacuum.htm (http://everist.org/NobLog/20151112_planning_vacuum.htm)   "20151202 Wednesday"
So I do have a very slight need for a printer atm. Was going to do it at someone else's place who does have a printer.

Didn't get any manuals...but I found most of them online.

I also got several solder stations...and this bad boy I forgot to mention...

A Fluke 3330B Calibrator!!!

I just discovered I had misses it last night.   

And an Eico 150 signal tracer.


I have some machinist bits and such I acquired over the years I have no use for...and am bringing them out to the man...as its his other hobby.  I have a feeling I will come home with more goodies next weekend.

Fluke 233 advertised as faulty, only displays "----". Problem turned out to be the IR LED in the display had lifted off the PCB taking the pads with it. Glued it back down, added some bodge wires and it works flawlessly  :-+

I thought I posted this one before, but I can't find it. So...

Was given a Fluke 123 Scopemeter that wouldn't power on. Did some Googling and found that the keypad membrane was a common fault. Disassembled, cleaned with IPA and applied DeOxit. It worked for one week then wouldn't power on again. Paid about $70 for a new keypad "foil" from the Scopemeter guy. Still working just fine after six months or so.

The battery pack was also dead. Did not want to pay the price that Fluke wanted. Even the Scopemeter guy gets a bit of money for a lousy NiCad pack. Took the old pack to the local Batteries Plus store and paid $12 to have them rebuild the pack. Rebuilt battery pack also still working great.

Those old HP p/s are built like tanks. Work great! I have an old Lambda LH125FM and an Electronics Research Associates Model 110MC 0-100VDC p/s that I paid $25 for from Tucker Electronics in Dallas. Tough units and work like new. AND you can repair them if something happens.

Turns out the lithium battery in the unit was removed.

Pretty neat unit for 10 bucks.

This probably doesn't fall under the category of "test equipment", but I got a good deal on a pretty cool robot arm (Staubli TX40) on top of a big Newport optical table.  I bought the whole thing for $1600 at an asset liquidation auction for a pharmaceutical company.  I've fired it up to make sure it works, now I just need to think of something fun to do with it.   :)

There's something about the idea of a cutting laser on the end of a multi-axis robot arm, that seems a little risky.

Yes, quite dangerous, especially when it is is collimated.
That's another benefit of CO2 or YAG laser -- invisible, and stray light (i.e., not coming directly from lens) won't hurt your eyes.
But I assume the owner has VERY deep knowledge in laser, as we can see the table with optical mounting holes -- probably a professional optical engineer.

Still, play safe.

Free stuff:
Simpson 260-7 with a case.  Found at the dump, needed only a battery cover
Simpson 260-7P, sent to me for the shipping as a parts donor for the meter above.  Case was cracked, battery cover OK,  worked fine.
Sound Technologies ST1700A - cost some time to adjust it to spec.  Semi-permanant loan from a friend.

cheap stuff:

Simpson 260-2, $5, bad meter movement but a perfect case.  Case went on the 260-7, case from the 260-7 onto the 260-7P.  This was then given to someone else who needed a Series 2 parts meter.
BK 1540 scope, traded a used laptop hard drive for this.
Eico 667 tube tester - $25 at the flea market
Eico 378 audio generator - $10.  High THD, but good enough for signal tracing
RCA WV77E VTVM - $20, awesome for doing alignments on old radios
Triplett 2a AC ammeter, Weston 0-130 VAC meter in cool little cabinets - $5 each, perfect accessory for an autotransformer / variac
Superior Powerstat $10, because everyone needs an autotransformer
BK 1692 40 amp DC bench supply - $50

Not "cheap", but happy with it anyway

HP 3456A - $100, in nice shape
HP 8640B - $150, works perfectly, no problems with the tuning gears

Cheap, but not actually working

Singer spectrum analyzer - $5.  No horizontal sweep, but once I figure out the sawtooth generator the rest seems to work.  If its stable enough, this should be awesome for IF strip alignments.

I've considered getting ZD-985 version but I'm not sure I'd use it that much. I really wish I'd bought a Hakko 808 before they were gone. The 808 kit was selling for just over $200 right before the FR300 was announced. There's also a baseless unit (gun and stand only) on eBay that looks a lot like it for about half the cost.

Japanese is the second most studied foreign language in China, after English.

Also, in my hometown (Shenyang), which was Japanese command center during early WWII in China, Japanese is a popular secondary foreign language, as well as Korean (we have many Chinese nationality native Korean speakers).
In fact, I have 1/4 North Korean blood, despite I can not speak even a single Korean word, but I speak Japanese fluently.

That's remarkable. My knowledge in the Japanese language is limited to what I've read in "The Book of Five Rings" and the terminology used in Judo, which I practiced for 12 years (got up to brown belt).

I seriously admire how the Chinese are seeking world domination through knowledge.

I've also got a Simpson 260 either series 1 or 2, I don't remember which at the moment. That one was a swap meet pickup for 5 dollars. I've not messed with that one due to it having a kind of sticky movement, but it's in good shape too.

And for the 3rd analog meter, I have a Triplett 630. That one needs a new 72 meg wire wound for the high voltage range.

Not much of a score, but I picked up a Tek A6302 current probe with a TM501 and AM503 for a couple hundred.  I wasn't too happy when the TM501 was bashed in shipping and the AM503 was nonfunctional until another auction for just the probe went for $300.  The probe works fine (I had a couple of other AM503s kicking around and was able to verify that) so I think I'll call it good, bash the 501 back into shape and use the 503 for parts.

Got a Tek 321a for $35.  I always liked the Tek ceramic strip construction, but wasn't fond of vacuum tubes.  This is an all transistor (except for a  nuvistor input stage) 6MHz scope.  You can even run it off of D batteries (for 1/2 hour).  I needed another scope like a hole in the head, but this is a work of art.  It's semifunctional (there's a trace), but needs work.  A nice project for a day off if I ever get one.

An Icom IC215, with a full set of crystals, and of course a dead audio power amplifier stage. Going to pick up a few UPC 575 audio amplifiers at a local store if they still have them this weekend. as the old one has a hole in it. Will pick up a set of capacitors as well, Icom used 10V capacitors on it in the output stage, and I want to replace them ( along with the other power capacitors) with 16V ones, along with putting a new output socket on it, and a decent power input protection, using a power ( old PC PSU one so free) diode. Plus replace the magic missing screws, and tidy it up a little.

Might even try to see if I will put the battery pack in it, but might use the space for other uses and make it a desktop unit. Icom made this thing with a power input centre negative.......

Agilent 6632B power supply sold for parts and not working. The ad stated the unit displayed "BAD INT" and then turned off. I noticed in one of the pics that the input voltage was listed as 220V with a black sharpie marker. I figured I had at least 50/50 odds the supply was tested on 120 VAC but wired for 220 VAC. I threw in a best offer of 25 bucks and it was accepted. Received the supply today, powered it on and sure enough I got the "BAD INT". I then opened it up and verified it was wired for 220 VAC. I moved the jumpers to 120VAC and it now powers up and works perfect. Did a quick cleaning to it. I now have a nice 0-20 volt 5 amp power supply that will also sink up to 100 watts.

Curiously, it was cheaper to get the 16702a with a screen than a 16700a that wasn't a stripped chassis without.

HP8711B .3 through 1300 MHz network analyzer for $300.00 plus shipping - however it doesn't turn on. So it will either be a great score, or a big paperweight.
Seller had it listed for $650 or best offer, thought I'd throw out a cheeky $300.00 and it was instantly accepted. It is always good to have a stack of projects waiting.

That is a good price, Steve. Hopefully, you can get it working without too much trouble.

As for stacks of projects, I think I'm doing too well in that department. Oy! :-/O

If you think you can fix one keep your eye on ebay. It helps if you happen to have a friend in the area who might already have test equipment. And I'd try to find one where the problem is likely power supply related. Then you have a pretty good chance of the RF portion being good once you fix the power supply problem. Troubleshooting RF problems generally requires lots of other RF goodies.

I got a really, really nice HP 8648C signal generator with the high stability timebase for $600.  The guy told me they bought it new years ago and was never used.  It is scratched on the trim ring from storage but otherwise perfect.  I know $600 is a lot for a 'score' but these things are still pretty pricey. The guy said he's had 5 calls for it after mine and true to his word, he held if for me while I was out of town.  Picked it up yesterday and tested it and it seems to be perfectly calibrated.

Anyway, I did some googling and it turns out Fluke simply bought Wavetek. Mystery solved. Interestingly, the same clamp is also sold under the Amprobe brand (another Danaher subsidiary) with identical specs as the CT238A, for $60 less than the Fluke i30.

Pretty cool. :-+ A clamp in that range is next on my list. Although the i410 has the worst specs of all the Fluke ones and is the only one that doesn't have a Wavetek equivalent. I think it's part of Fluke's strategy to come up with their own designs and have them produced in China. Like how the old probes and leads were made by Pomona and the new ones are made in China. Here's a teardown:

My score today is not test equipment, but it's related. Maybe these will end up powering my test gear?

20160331 Thur

Being given 8 big solar panels

I walked the few houses up to the shops to get milk for my breakfast this morning. On the way back, there was a van parked almost directly opposite my house. A guy was loading what were obviously old solar panels into the van, with a couple still leaning against the front street fence still to go in the van.
Ladder against a house there, shiny new panels on the roof.

On the principle 'grasp potential opportunities in the moment', and that he was obviously finishing up and about to leave, I quickly walked over and said hi, are you disposing of those panels, and could I possibly have them?
I then went into detail, about being a retired electronics engineer, and wanting to examine a bunch of old panels to see how they degraded, what kinds of faults, etc.

He had to phone his office to ask, and while waiting for them to call back he explained they were a warranty replacement, since the house had been struck by lightning, and they were probably dead. I said I didn't care, in fact that made them more interesting. (I was thinking it unlikely they were ALL dead, plus I would actually like to see the result of lightning-struck solar panels.) I asked how often that happened, and he mentioned only ever having had to do this about 6 times, in several years.
We talked about the idea of mini-inverters per panel with 240VAC outputs in parallel, vs panels in series and one bulk inverter. I mentioned the idea of a system with sense wires to each panel, logging stats of individual panels. He says there is such a thing, google "Tigo".  Got his business card.

We stacked the panels against my front fence. He asked if I had a multimeter and I laughed and offered to show him my electronics workshop. But he was in a rush to another job and had to leave. He gave me the box of mounting hardware, and a couple of rails. he'd installed only 6 new panels, presumably higher efficiency equivalent to the 8 old ones.
I moved the panels to the side of the house, then had breakfast. Afterwards moved them to the back yard, laid out in the sun. Cloudless sunny day atm. By 11:30am I'd tested each one and recorded values. Open circuit V, and short circuit Amps only. Wrote values on panel frames in marker pen, then copied to paper, numbered them on paper in rough order of functionality, then wrote the unit numbers on the panels too.

The sorted data:
   Voc    Isc(A)
1  30.0   8.2
2  29.7   7.2
3  29.9   6.2
4  20.2   8.0
5  20.6   7.3
6  20.3   7.2
7  19.9   7.4
8  10.3   6.5

Number 8 is pretty dead, the others all seem not bad, and quite worth using.
Figures taken with the panels manually tilted up to approximately point at the sun. But a few minor shadings - long grass, clothes hoist, etc.

They all have some dirt on the glass, and small lichen growths. Cleaning them may improve the figures a bit.

One good, 2 with a single dead cell, 4 with around one third dead and the last one with almost all dead. Must have been the one that took the hit. Still, with the price you paid you can always use it as a 2s liopo charge system, providing a nice convenient source of power. 

Rest will need either micro inverters or a boost converter to go partly off grid, and either offset your bill or just have a solar section in the house, or power your shed equipment. 600VA of power will do a nice little offset of the electric bill, especially if you now can grab a free grid tie inverter that will work off a 120V panel string.

hmm for most of you it is not test equipment but for me it is :)

I got a few Garmin Marine items sold for Parts on eBay. So a Garmin 8012 Marine GPS (current 12" model - cost around $6000 new) and a Garmin Radar 18xHD - latest model. Both was listed "for parts" - and right enough Garmin 8012 died after 5 min power on. But it was still under warranty and a replacement arrived within 2 weeks... :) And Radar worked perfectly. Total price for both - about US$650 all inclusive vs about US$7500 retail)

Most people do not know Garmin has a pretty good out of warranty service - so worst case the 8012 would have cost me USD$1000 to get replaced with a refurbished model.

So not really a big gamble but a big win as I do now have a complete Garmin test setup for my "things" i'm working on

@Terrahertz: your next score must be a lawn mower  >:D

Ha ha. Yes, it's very long. In the back yard, both I and the cats like long grass. But out the front it's a bit of an embarrassment. I have three lawnmowers, all with various faults I can't be bothered fixing. (And actually, some are a bit mystifying; I'm not a good 2-stroke mechanic.)

Here's the joke: Among that house-clearout pile of stuff recently, there is another lawnmower. However my friend said "It was working fine, then last time I tried it wouldn't start. Don't know why." So now I have FOUR broken lawnmowers. At least this one is probably just a dirty plug or something simple.

The 'fix a mower and mow the damned lawn' job is working up to close to the top of the list.

LEM made/makes current clamps for fluke, including their high freq. (50Mhz) one.

Thanks, specs look identical to the Fluke i30, so I'm not sure what you mean by slower?

http://www.farnell.com/datasheets/317094.pdf (http://www.farnell.com/datasheets/317094.pdf)

And how is it inaccurate? E.g., a multimeter like the Fluke 17B+ has an accuracy of +/- 1.5% +/- 3mA on the 4A range, the Fluke/Wavetek/LEM current clamp has +/- 1% +/- 2mA, so that is actually better. Does yours not meet that spec?

By the way, Fluke bought Wavetek in 2000 and LEM in 2005, so they could've been selling the Wavetek under the LEM name. Do you know the manufacture date of your model?

Mine should arrive this week, I'll definitely have a look at the PCB.

There is a similar one around with around 100Khz BW, i thought fluke would have this one.
Yes, it does meet its spec, it is a bit drifty (within spec) and well, its not a precision current transducer like LEM IT series for example. But it certainly works for most purposes, except those where high precision is needed, where one would use a high grade shunt or transducer.

Oh, btw, it does like to eat batteries. That slide switch comes on sometimes upon putting it into a drawer, and it doesnt have any kind of auto-off. Sucks the battery down to 0,1V.

Board says PR 20 Issue G, Date codes are around 2001-2002.

Ah, I see what you mean. There are two versions of these clamps: with 4mm plugs and with a BNC plug. The 4mm plug version is specced at 20kHz, the BNC plug version is specced at 100kHz, but apparently, they're identical internally except for the cable:

Does it drift by itself or only when you move it? Yes, you can tell they never changed the circuit, the specs for all versions/manufacturers claim a 30 hour battery life ...

Most drift was from opening/closing the clamp. I did just clean the mating surfaces which did improve that quite significantly.
There is a bit of LF noise remaining, but thats what to expect from anyhing hall based.

Also note my edit above, almost certainly its designed as a PR20 as the board says just that. Fluke also did stick their label on many other LEM designed probes, most of which are pretty good. Also, LEM bought up a lot of other companies back then (like NORMA, who made excellent power analyzers, which was closed down soon after), so the probes origins probably are around whatever HEME was.

Post by: robert_ on April 05, 2016, 10:05:08 pm
Just did a quick+dirty BW measurement on the PR20: -3db is around 180Khz on mine, pretty flat out to 100Khz with a bit of peaking beyond that.
So there is no difference between the i30 and i30s except for the cable.
Gonna install a BNC cable on mine to make it more useful and possibly couple less noise than with the unshielded one+adaptor.

Picked up a nice Tek 485 350MHz scope for $35 the other day at my local university surplus outlet.  Doesn't work, the power supply is a switcher in tick mode, so that should be a fun project.  Probably a bad tantalum somewhere.

Sometimes the deals are great, sometimes they just have junk.  I was looking at a 4 channel LeCroy, but there was a list of issues taped to it and the screen burn was awful. The guy behind me picked that one up  :-DD

I just scored 6 panels like yours today for $100 and one panel was faulty. I have been able to resurrect it by replacing the failed diode in it. The panel was only giving out about 2/3 it's normal voltage because the diode had gone short.

I was going to bid on eBay.de today for HP 8591A with tracking generator. I said to myself 820€ is adequate. 3 seconds before end I clicked BID and then
Dieser Artikel kann leider nicht nach Tschechische Republik verschickt werden.
[...]
Todays lesson: Always place some test bid, something like 1€ higher long before auction end.

Had something similar with a Tek DPO5034; ended up doing a test-bid, and figured out the seller wouldn't ship to Germany. Created an US account, and shipped to a friend. Ended up paying $5133 (~4.5k EUR back then), which was a pretty good deal - at least if you like Tektronix scopes.

HP 4262A LCR meter.  Don't know why they are typically so expensive ($500USD) on eBay, but I bid on one and got it for around $150.  It was sold as 'parts or not working'.  I powered it up, fixed the first problem with missing segments in the display by reseating the cards.  The next problem took 16hrs of debugging but it turned out to be a shorting strap on the terminals (for 4w) that wasn't shorting.  Nice meter, pretty consistent down to the 10th of a picofarad repeatability.  Been looking for an LCR for a while.

The sorted data:
   Voc    Isc(A)
1  30.0   8.2
2  29.7   7.2
3  29.9   6.2
4  20.2   8.0
5  20.6   7.3
6  20.3   7.2
7  19.9   7.4
8  10.3   6.5

Number 8 is pretty dead, the others all seem not bad, and quite worth using.
Figures taken with the panels manually tilted up to approximately point at the sun. But a few minor shadings - long grass, clothes hoist, etc.


I just scored 6 panels like yours today for $100 and one panel was faulty. I have been able to resurrect it by replacing the failed diode in it. The panel was only giving out about 2/3 it's normal voltage because the diode had gone short.

Thanks for the tip! At the time I didn't open the terminal boxes, and had forgotten there were diodes in there. (To take the current past cell strings that are shaded, so they don't get reverse biased and damaged.)
I had noticed that the voltages were all close to 30V, 20V or 10V, so wondered if there was some 'rule of thirds' happening.  In my defense I would have figured this out once I got around to opening the junction boxes up. Was just in a hurry that day, and stacked the panels away under cover.

I PM'd you. Said I'd check my panels next week when current urgent chores done. But then, I couldn't wait. Just now opened up panel #8 (the worst one.)

Could tell by eye there's a diode problem - one of the three has leads discoloured slightly by heat, and has an 'extrusion'.
They are only clipped in. Pulled them out and measured them:
 Diode 1 (discoloured) 364 ohms both ways.
 Diode 2  dead short
 Diode 3  dead short

So the output from this panel was the result of two shorted strings, and one string driving a resistive load of 364 ohms. (Heating it up quite a bit.)

Also cleaned the lichen off the glass. Mold-killer spray, scourer pad, then hosed off. Easy.
Too bad it's evening now. In room fluro lighting without the diodes, the three cell strings (each 18 cells in series) produce 5.87V, 5.99V, 6.4V.
Pretty close. Differences likely mostly due to uneven lighting across the panel.

The diodes are 12SQ045   ( Schottky, 12A 45V, Vf=0.55V@10A )  Commonly available.
Ordered 50 for US$15 via aliexpress

With luck, maybe I'll have 8 perfectly good panels.  Woo hoo!

20160420  Edit to add: Had some free time and it's a sunny day, so I took panel #8 outside in the sun and measured output without the dead diodes. Voc=31.9V, Isc=8.03A  Excellent!

I can't wait till the 50 new diodes arrive. I'll leave retesting all the panels till then, since I don't want to open the junction boxes twice. They use plastic lid retaining clips; I'm afraid of breakages if I keep playing with them.
Once they are all fixed I'll measure them under load at max power operating point.

Edit on 20160510 to add: Started a thread over here: https://www.eevblog.com/forum/renewable-energy/solar-electric-panels-vs-lightning-emp/ (https://www.eevblog.com/forum/renewable-energy/solar-electric-panels-vs-lightning-emp/) to update on those panels. Some nice pics of EMP arc-tracking on the cells. But the panels all work!

I find a decade box to one of the most useful pieces of gear.  I've plotted mine so I have a good idea of its calibration and I can check my meters regularly.  I have an ESI that is incredibly accurate and stable.  I don't know why they combine resistances though, there is an economy in the box that I haven't taken the time to understand, but even so, the wire wound resistors are very stable.

Hi,

I am just back from a trip to Silicon Valley. I made some special arrangements so I could attend the Electronics Fleamarket at D'Anza College in Cupertino, CA.
Details of the market can be found here:

http://www.electronicsfleamarket.com/ (http://www.electronicsfleamarket.com/)

I managed to find one of the items on my want list, a set of cables for an HP4155B Semiconductor Parameter analyzer. These use Triaxial cables and connectors. The connectors look like BNCs, from a distance but are quite different. They are used on HP Semiconductor Parameter analyzers and some Keithley SMUs.

This is what I found:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=217864;image)

The diecast box, has Triaxial connectors on one side and BNCs on the other. There were four cables attached.


The box had a price tag from Weirdstuff. (www.weirdstuff.com (http://www.weirdstuff.com)) a Sunnyvale surplus store, indicating the box had been priced at $5.00 in 2006. I don't know when  it was bought or if the price was for the box or the complete assembly.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=217866;image)

Here is a close up showing the Triaxial connector.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=217868;image)


I knew I had the right thing when I found the labels on the box 'SMU1', 'SMU2'....

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=217870;image)


I bought the whole thing for $5.00. I was really pleased to get this. ;D I can make proper use of my HP4155b shown in this thread:

https://www.eevblog.com/forum/testgear/hp-4155b-semiconductor-parameter-analyzer-smu-need-master-disk/msg713021/#msg713021 (https://www.eevblog.com/forum/testgear/hp-4155b-semiconductor-parameter-analyzer-smu-need-master-disk/msg713021/#msg713021)

Mine was a Tektronix TDS3054 in the works auction for about £70 a couple of years back. It was in cosmetically good condition but the display was dimming.
It didn't take me long to work out how to reprogram the EEPROM in the module slot to unlock all options :)
It still works great now.

The pulse generator was built here in SanDiego I love the case and knobs. All aluminum anodized and V-honed to give the flat look.
The scope is going to have to be re-capped, there is quite a bit of jitter in the triggering circuit. I think the pulse generator also needs a bit of work.

I have tow Tek 475s in the garage both not working, one was a parts mule to get a third 475 working The other one in the garage is in fairly good shape and has a DM-44 attached to it.

Not sure why I had been wanting a Simpson 360, but I finally got one for pretty cheap off that auction site. Silk screen lettering is falling off and the bakalite case has "oxidation".

Just so happened that there was also an auction for a NOS front panel that I got for a great price.

The meter works, but needs new battery terminals as they were destroyed by the leaked acid from the cells.

The case will clean up pretty quickly and easily with some Mother's Aluminum Polish.

Just picked up a pendulum CNT-85 Frequency counter from a local auction. Has the GPIB, 3GHz input and ovenized oscillator (It is the same as a fluke PM6685). Paid $135 after fees.

I picked it up, got back to the workshop, opened it up and checked for anything nasty. Plugged it in and..... Nothing :(

Checked the fuse, fuse was OK. No 240VAC coming into the test points, no 240VAC coming onto the board. Schaffner power filter had gone open circuit. Replaced it with a new one and it powered up straight away. Theres a few scratches and marks on the case, but all in all I got a bargain.

Congratz !
However, I found myself drowning in huge amounts of useless components looted in few years. I bought so many elytes and boxes of variety of components on flea markets and local auctions/local ebay last years. Useful is only a fraction of them, like standard elyte and resistor values so when I am building something I always have to buy majority of components.
Anyway, I am always happy when some of my friends bring me full seals of SMD components swept off the floor in assembly factory (assembly machine errors/rejects).  ;D Resistors and capacitor I dont sort, easily identified semiconductors like BAV199 or 1GHz MMIC are OK.

Cheers.

Not quite test equipment, but found a choice piece of Hakko gear.

Apparently unused Hakko FM-203 setup with the FM-2030 140W iron and a bag of tips, for 220$ shipped.

Sadly, the included tips are all T15 series. So off to buy an FM-2027 iron (and a T22 tip or two for the overkill iron).

Powers up and tested with a friend's FM-2027 iron. All is well and I'm set for the next decade or more  8) (or until I decide to really go stupid and look for an FM-206)

Hi,

Here is my latest score, a Fluke 720A Kelvin-Varley Voltage Divider.  Picked this up at the Dayton Hamvention for the price of $30.00. Here are a few pictures

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=227022;image)


I applied 10V from a Fluke 732A dc voltage standard and measured the output with a Datron 1281 DMM:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=227026;image)



The Fluke 732A reads about 5pmm high when connected directly to the Datron DMM so it looks like the 720A is working nicely.

I have not been through the adjustment procedure.

:-DD  The 5245L was the beginning of my nixie addiction.   :-+  I'd say you got a good deal at $40.

Congrats.  What else resides in the stack it will be joining?

I have both a 3450A and a 3450B multifunction meters.  Took me a year to track one of those down after seeing a thread on it in this forum.  Someone had pulled the display board, so I picked up the second one, then found a display board on Ebay, so I have both functional.

Prema 5000 6.5 digit DMM for 15 euro's at a hamfest. The guy selling it only read scanner (which isn't even there) and not DMM/scanner.

Mind you it is three times more than i payed for the first one (yes, got two now)  8)

Got a KEPCO BOP 100-1M for $175. Was listed for parts, as there was no output. Unfortunately the "fault" was trivial (I like the troubleshooting and repair process), the strapping from positive output to sense was missing. Apparently the instrument has a safety against operating in that state.
In any case I now have a +-100V/1A, four quadrant power supply for the bench. I'd love to have a copy of the service manual for the instrument, but Kepco charge $200 for it.

Yeah - though in fairness this is a still-current instrument, they'll sell you a brand new one for ~3K list, and having the service manual generally available for a charge is also IMHO much preferable to no availability. Still, $200 seems a little steep :).

I scored one of these Thurlby Thandar TTI 1906 Multimeters for a fair price and the seller was able to provide the history on the unit so I was a bit more comfortable with the purchase, I could not find any reference to them anywhere in regards to teardown pictures or much in the way of usability although I did however study both the user and service manuals prior to the purchase and will take a few pictures once it arrives. In the process of researching these units I have also gathered a fair bit of information on the entire TTI range of multimeters so I might start a thread in the test equipment section once it's all collated.

Nothing exciting, but finally picked up up a nice old variac from a local garage sale, only mentioning it because it went for £10 as opposed to six times that and I'm cheap enough to keep searching for two years to save that much.
Also some lovely metal parts drawers (unfortunately only after forking out for a couple of plastic ones from Aldi as a standby).

These were from a local machine engineer where luckily most of his impressive collection of machines went into the care of hobbyists, rather than some clearance gypo just buying the lot to sell.

Apparently a few buyers mooted that their own hoards of specialised stuff really needed to be passed on to the right people now, rather than it all being left to their families to dispose of without understanding its value.

Sad to see a box of reamers and micrometers just sitting there, just waiting for the right guy to turn up.

Interesting little meter, ...........and super duper power efficient too as it can even measure when turned off !  :D.
Im guessing yours will turn out to be a later revision which requires mains to be not only plugged in but the power switch be depressed to on for measurements.  :D :D

Seriously though ... would be interesting to see under the hood.

Post by: Muttley Snickers on June 06, 2016, 02:48:47 pm
They are a bit of an odd-ball thing, also sold as the Racal-Dana 4006 with a darker case and side handle which the TTI's also had in earlier releases, I was on the hunt for a Yokogawa but the prices are just way over the top and then this thing popped up and was initially passed in and after correspondence with the seller it seemed like a good deal so I jumped on it.

I was initially put off by the AC counts which are a bit ordinary but I don't do much with AC anyway so it won't be an issue, the RS 2007 catalogue has these listed for $1200 and the Farnell book from the same era was at $1800, these were the only prices I could find new other than some Ebay listings at around $600, anyway I paid bugger all really.

1.5 LeCroy AP015 current probes for around 400eur
One complete, one missing case and transformer, sold as untested.
I did hope that at least the connector works on at least one, as the probe itself is identical with my Fluke i50s (which in turn is made by LEM) and could be transplanted to it, as to finally have a nice solution that doesnt need external power and gets the scaling right.

Now, all that stuff was seriuosly dirty, full of iron oxide. Stil, the complete probe worked, after cleaning the transformer and trimming the gain a little, it seems to be perfectly in spec!
The other one actually works too after installing a transformer from the working one, but would need to be calibrated. So i took the whole probe from my i50s and transplanted it onto the AP015 plug, which was successful and also works in-spec.

So, 2 working AP015 for 400+300 (that i50s)Eur. Not too bad a price...

Bought a DSOX3014A from the Keysight ebay store. It came with no probes which was fine with me. I picked up four 500 MHz 1161A miniature probes like new in the padded zipper cases with all accessories for $40.00 each. Looking at the 1160A series of probes they just ooze quality compared to the newer current model probes.
Also came across a proper DSOX3000 series N6450-60001 Logic Analyzer cable for $90.00.

Yes, I am using them with my DSOX3014A. 10:1 is correctly selected and the 50 termination option menu is removed. The probe compensation was also no problem, 2 of the 4 required no adjustment at all. I wasn't sure they would work but thought it was a worth a shot at the buy it now pricing. I can't believe all the accessories that are included with these probes - even spare probe tips. The padded/zippered case is even made in the US and would probably cost more to have made today then to make the current probes Keysight sells.

Did the usual check the mains circuits, check the PSU rails, checked the HV  - all ok.
Looked at the horizontal amp , the leads to the final transistors where no longer "clipped" into the PCB, pushed them in and Voila!

I hope I scored something nice from Ebay today after some haggling: an Anritsu MS4630B 10Hz to 300MHz network analyzer.
(http://gwdata.cdn-anritsu.com/images/products/tm-ms4630b/ms4630b-networkanalyzer.png)
There is one problem with the one I got though: it doesn't power up but the seller (and equipment dealer) claims it stopped working recently. I just hope I didn't waste a couple of hundred dollars. Anyway, needing to repair it is a good reason for a teardown so expect that soon! I have never used a network analyzer before but I think it will be handy for an upcoming project and because it can also calculate the equivalent circuit so it can serve as a (not so precise) LCR meter over a wide frequency range.

A new toy arrived today: A Flir C2 thermal imager
(https://ivytools.files.wordpress.com/2015/01/flir-c2-thermal-camera.jpg)
which I bought as good as new with a 60% discount from Toploser. With 80x60 it is not high res but I did some tests and it seems adequate for checking boards with 0603 (and bigger) parts. This is going to be handy to check boards for potential thermal issues.

My shopping spree ain't over and I saved listing the best buy for last! All the recent chatter about spectrum analysers made me want to upgrade my existing spectrum analyser to one with a color screen and preferably dumping screendumps onto USB. Actually I wanted to do that for a long time but never got round to hunting one down. Ofcourse there are the cheap Chinese spectrum analysers but I wanted at least 3GHz which means hacking or spending. So I went out for a hunt on Ebay and a couple of days ago I found some sellers with an Advantest R3477 Signal Analyser. Some digging in the manuals and pictures from various Ebay auctions made clear that this is not just a transmitter tester but actually a full fledged spectrum analyser with signal analysis features bolted on. After some research and haggling I got one for the going rate:
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=238868;image)
I'm pretty stoked about this buy. It seems several Korean Ebay sellers are unloading a big stack of these machines and their going price is around $1400 each including a 14 day warranty. Does that sound right? A spectrum analyser with USB, LAN, big 8.4" touch screen and 13GHz bandwidth for $1400 not in 'for parts' condition? I guess it does... Now someone probably chimes in and says these machine crash and burn all the time but until then I'm confident it will be fine just as my current and previous Advantest spectrum analysers.

I'll do a partial teardown because no way I'm going to open or even disconnect the RF moduls if I don't have to!
OTOH the R3477 runs on embedded XP so I want to make a backup of the hard drive for sure. Also some components have a limited lifetime (Advantest is very open about that! In their manual they have a list of guaranteed lifetimes for batteries, backlights, electrolytic capacitors, etc) so I want to check those as well.

I think this is by far the best deal on a color SA with USB.
Congratulations.

7 years ago I paid Euro 6500 for an older 12 GHz HP SA.
It works great but is a pain to get a screen shot over the GPIB and no color either.
You got a great deal!

Very interesting! Are you going to start a thread in test equipment about your progress with this one? I'd really like to follow that, since I've never owned a working spectrum analyzer, or even used one, I'd like to, and this price range is something I could stretch to.

Years ago I acquired a couple of very old HP 141T frames, various plugins, and the manuals. Thinking I'd get them working as a learning experience and I could live with the old no-processor style. But that was a bit too ambitious for someone with zero RF experience and many other time sinks.

Ha funny - I could afford one if I sell a couple of my GRC-106 radio sets. But, one obstacle to selling them is that I need a known-good spectrum analyzer/radio test set to check results of my unskilled antique radio refurbishing attempts. Classic chicken and egg problem.

That's true, AFAIK you shouldn't manipulate with SMA connector with signal more than 4GHz.
Yeah I look forward to teardown, I love these Advantests. I have R3361A and I like it a lot.

I see that you are from Belgium, my home country.

Where about in Belgium are you based?

Do these scopes come from a university? Which one? Or where do they originate from?

When was the last time they were calibrated? Do they come with a calibration tag?

Are you selling them off through Ebay or are you keeping all of them?

Will you subject them to a basic test before you sell them off?

I might be interested to get one for a friend in Belgium, that is setting up a hobby electronics lab,
depending on the condition and the asking price :)

Well, I'll be selling them off, either here on the forum, eBay, to contacts etc.etc. Bought them at an auction in the US, surplus lab equipment (or bankruptcy?  :-//) from WD (well they are not bankrupt  :-DD) and Celestica.

If past experiences are anything to go by, these come from big companies with quality handbooks so they probably were calibrated yearly untill they were taken out of rotation. Which may be 5+ years ago.

I test unit for basic functionality (ie does it display a waveform) and run all the selftests available. Other stuff on request and if I can.

Picked up a really, really nice HP 8566B locally today.  I think it was a steal at $500USD.  Has the cables, display unit, complete. I thought my 8568B was a great deal and low and behold, this thing showed up on craigs list.  I am just sitting here amazed.  (Have to sit because I strained my back putting it on the bench).  Thanks to Orin for not talking me out of it. :clap:

So now I'm wondering if my 85685 preselector will work with it?  I also have an 8444 with option 059 that I would like to use in the 0-2G for tracking but the IF is different so I need to figure out a tracking generator.  I've seen all the posts and youtubes on how to make one so I guess I'll go hunting. 

Setting aside how heavy these units are, I find it difficult to believe people would rather buy a Rigol for 3X the price of this thing.

Picked up a really, really nice HP 8566B locally today.  I think it was a steal at $500USD.  Has the cables, display unit, complete. I thought my 8568B was a great deal and low and behold, this thing showed up on craigs list.  I am just sitting here amazed.

I find it difficult to believe people would rather buy a Rigol for 3X the price of this thing.

Btw, see ebay 391505546407  HP 8566B Spectrum Analyzer (REPAIR/PARTS)  US $399.99
I'd be really tempted, if I had the money now. Which I don't.

How does the HP 8566B perform against the Rigol DSA815-TG or Siglent SSA3021X in terms of the following?
- User interface friendliness
- Sweep speed
- Internal noise floor
- Spurious response

I have a HP 8566B on its way in the mail as we speak.

Its difficult to compare it to the rigol due to the way they specify noise and such, but they should be pretty close in performance apart from the bandwith and UI. The HP doesn't seam as intuitive but you do have a dedicated button for almost everything rather than digging trough menus.

The HP 8566B is an old boat anchor but it does have some nice features. However the Advantest R3477 I bought recently is a much more modern one and you should be able to get a fully working one for around $1400 after waiting and haggling a bit.

I just picked a Tektronix 454A old school scope for audio work. Dirty as hell but in mint shape otherwise. Was owned by IBM at some point as their logo is on the front and sides with the rest of the lettering. Also have a vintage HP 711A, vacuum tube regulated power supply on the way, up to 500vDC @100ma, perfect for some low current plate circuits on vacuum tube gear.  :-+

This has been discussed at length.  There is no comparison between those two analyzers and the 8568b  or the 8566b.  The only thing they have going for them over the HP units is that you don't need a crane to move them. I think the UI on the HP is hard to beat.  I have an advantest as well with the TG and I hate having to hit multifunction buttons and menus to get anything done.  Also, I have the 85685 preselector and preamp and with that combo the noise floor is incredibly low.

I got a HP 6623A power supply sold as non working for $106 delivered (only bidder in an auction). I cleaned the keypad and checked everything, all 3 channels work well. I think what helped is that the auction pictures made it look way worse than it actually was, poor thing looks like it fell off a truck.

Considering Microlease is still trying to get nearly 12K for them, it's a hell of a deal.

Someone locally had racks of HP power supplies, all of them high wattage, on craigslist.   I just didn't have the room.

The best dumpster score I ever experienced. A very rare opportunity (at least here in my country) to found something so valuable that would even cost a few thousands of peso for a brand new one. Its an Hioki 3256-50 Multimeter. Its was dead but turned out to be the only issue was the board wasn't held by one of the clip post that has been bent for a long time since the board popped out. A simple board cleaning, re installation and reinforcing the bent clip post with a piece of paper fixed the issue..now I feel great to have additional multimeter to play with.

Not so much a work bench but a newly acquired storage area for some test equipment, stereo gear and other stuff, a customer had this cabinet sitting in his garage and had intentions of going at it with a chainsaw as nobody wanted it and they are worth nothing much nowadays anyway, I explained that I may have a use for it and as it turned out I did, the thing is huge at about 2500 long, 1500 high, 560 deep and weighs 3 crushed vertebrae (a new unit of measure).

I gave it a good clean and replaced a couple of wheels so it is now easy to move about for cleaning and getting to any cables I might add at the rear, I have a couple of shelves to add over the weekend and it also came with a nifty multimeter rack with adjustable shelves, lead storage drawer and everything.

I’m saving the forests one cabinet at a time.

It's surprisingly true, the word quickly got around that I was looking for a decent timber storage cabinet for equipment and I had my eyes on the one pictured below which is still at our local recycle center for $50, I then discovered that they are listed on Ebay and Gumtree starting at a dollar and being passed in or free to good home with a fire place, as well as being left out on nature strips in front of peoples houses and this is where I scored the additional large pine shelves for the unit I now have, nobody really wants them anymore and are switching over to low profile cabinets with huge plasma and LCD screens sitting on top or hanging on the wall. I don't mind pine stuff as long as it's solid and well built and if there was more room about the place then I could easily fill it for next to nothing, damn shame really.

Thanks for the idea but I only have 880mm or 34.64 inches across the centre gap and have already started to prepare adjustable height full width shelves for scopes and other gear, the left door storage area will have some rack mount gear in it including a PC and I'm still working out what should go where.

The concern is that I could easily fill another two cabinets of this size with other gadgets without any problem, I expect the greatest benefit will be having frequently used equipment located at hand in one place rather than having to search through various lockers, cabinets and drawers which is starting to become a real chore.

The glass doors look nice - removing them would make for more usable equipment shelving though I suppose it depends it you're using it for storage and display of rarely used equipment versus for regular working access.

I've gotten some OK-ish bargains recently. Fluke 289 DMM for AU$150. Doesn't hold memory when the batteries are removed (super cap is leaky and a well known problem). Next digikey order I will order some replacement caps. The 289 needed a good clean, but is bang on with everything I've thrown at it.

I have a fluke 1587 insulation tester on it's way to me. Looks to be in good nick, cal sticker showed that it was cal'd about 12 months ago, paid AU$300 shipped. Hopefully I'll have that one in my hands in a few days.

Won a HP 66332A 20v / 5a PSU for AU$250 including shipping. Will be a while before that is on my bench, but looking forward to it.

A little while ago I also got a TTi PLH120 DC power supply. Capable of 750.0mA in it's high current range, then 75.00mA on it's low current. It is pretty handy to have a power supply that can go to 120VDC and gives you a readout to 10uA in low current range. I love the TTi gear and this is no exemption. Paid about $350 for it and it had only been used a few times, so a lot cheaper than buying a brand new one.

I'm interested to see the 8500 - I picked up one of those at a hamvention for $10 in poor condition. It was BER so I'm retasking its chassis as a case for a GPSDO and frequency divider/distributor.

@TSL:

Yes, the 5221A looks like new.  It probably did not meets the needs of the lab and probably sat in a box for dozens of years.  I believe it
was the late 90's or early 2000's when my friend put in a bid on a some equipment and the 5221A was in the lot.
Here is a pic of my Fluke 8500A reading the voltage form an Analog Devices AD688BQ precision plus/minus 10V reference chip.
My 8500A only measures voltage and I am hoping to find a donor with the ohms, current and ac plug in boards.
Also is a pic of my Tektronix 7704A.  Luckily for me, all the vintage items are in very good condition.
The lighting is not good so the pictures did not turn out. I don't have  the photography gene...

I forgot to mention when I did some minor work on the scope last year, the bulbs were burned out in the row of switches so I replaced them with
red LED's.  Looks cool with the lights out.  ;D
The voltage calibrator wasn't working and it took a while to find a 7472 flip flop.  I was prepared to modify that area with a more readily available device
but a friend found one.  Only one he had.  I have never come across a 7472 on anything except in my 7704A.
I didn't have two blank plates to fill in the two center slots so I put a piece of plastic over a scrapped cage from the logic analyzer option.
It works well and I am happy with it even though it is big and heavy.

Unique piece of test gear, although it is ugly and has a curved top so you cannot easily stack them up. Dumb design in that regard.

Those are *really* nice little amplifiers. I picked one up awhile back at an auction for $100 in non-working condition. Turned out to be a burnt out regulator.

My latest bit of kit:

(http://timb.us/images/TDS754C.jpg)

Tek TDS 754C + 2 x P6205 750MHz Active Probes + 2 x P6139A 500Mhz Passive Probes

Free, thanks to rx8's generosity and my luck of the draw! I've currently got it sitting on the floor by my desk, until I get a shelf built to house all my test gear (I just can't fit anything else on the table behind my desk that most of my gear sits on). Thankfully, Tek designed most of their old Analog (and early Digital) scopes with feet on the rear, so you could use them on the floor pointing up.

Good catch! That must be the cleanest TDS700 series scope I have ever seen (and I did wash the one I had)!

Thanks! rx8 took very good care of it. I ended up blowing out some accumulated dust from the inside and washing the exterior (the case, rear panel, front panel, rubber keypad, front trim and knobs).

The only issue with it is the ground connection inside the sealed power filter module appears to be broken. So I ordered a male and female IEC connector from Mouser and rigged up a 3" cord extension with the ground lead broken out. The ground lead has a crimped ring connector on the end, which screws into the metal chassis.

I investigated replacing or opening the sealed filter module, but it was a complete pain in the ass to do, so the cord method seemed like the way to go.

I was going to replace the floppy with one of those USB Floppy Emulators, but I decided to finally get a decent GPIB adapter. In the mean time, I'm using the serial port to "print" hard copies right to my computer. (I wrote a simple Python script to listen on the serial port and save the raw data; I love that the scope can directly print in Post Script format, which OS X can open natively.)

I'm really enjoying the scope so far! Being able to see 1GHz signals is amazing. :D

You are going to love that TDS 754.  I upgraded my 744 to a 784 and I am pretty sure the 754 can be upgraded to at least a 784, possibly a 794.  The upgrade required removing 4 caps on the acquisition board and then a little trickery to reprogram it.  The upgrade also extended the memory.

My 744 is at least that clean and the shuttered CRT gives such a crisp display plus the colors are just beautiful.

Post by: rx8pilot on August 06, 2016, 03:50:52 pm
That scope was food on the table for me. Never met the original owner - I was owner 2 - but he/she probably did not use it much. The CRT is still rather bright and sharp. I kept it as dim as possible and used the VGA a lot to extend the life of it.

Solid performer. I never tried to upgrade to 1Ghz because I could not afford a mistake while I owned it. If I kept it, I would definitely try the TDS784 upgrade.

Hope it makes a big contribution to your projects.

You are going to love that TDS 754.  I upgraded my 744 to a 784 and I am pretty sure the 754 can be upgraded to at least a 784, possibly a 794.  The upgrade required removing 4 caps on the acquisition board and then a little trickery to reprogram it.  The upgrade also extended the memory.

My 744 is at least that clean and the shuttered CRT gives such a crisp display plus the colors are just beautiful.

Yes, I've been researching that upgrade and am seriously considering it. However, I don't have any 1GHz signal generators for the calibration, aside from the the 1ns output on my TG 501 Time Mark Generator, but the amplitude is only 250mV, so I'm not sure if that's enough?

I wonder what the cheapest 1GHz source with sufficient fidelity would be?

That scope was food on the table for me. Never met the original owner - I was owner 2 - but he/she probably did not use it much. The CRT is still rather bright and sharp. I kept it as dim as possible and used the VGA a lot to extend the life of it.

Solid performer. I never tried to upgrade to 1Ghz because I could not afford a mistake while I owned it. If I kept it, I would definitely try the TDS784 upgrade.

Hope it makes a big contribution to your projects.

Yeah, right now, since I've got it on the floor, I'm using a little 12" VGA monitor on the desk (made from an old laptop's LCD and one of those conversion kits from eBay), so I can easily look at waveforms while probing. I've got it on a swing arm which makes it super handy!

I do really like the CRT+LCD Shutter though. It took me awhile to get used to it (I kept seeing it flicker in the corner of my eye or when moving) but after using it for awhile I don't even notice it anymore. It's a very bright, crisp, fast display.

Reading about these scopes, I see a lot of people ragging on Tek for using the CRT+Shutter system and I'm sure they had some issues, but for the time these scopes were built, I have to say it was a very nice display technology. You get the crispness and speed of a monochrome CRT with super vibrant colors! At the time, color LCDs were atrocious and I don't think they could get the same resolution and clarity out of a color CRT that small.

Anyway, I think I'll try the 784C upgrade once I get the signal generator needed to calibrate it.

And yes, I'm already putting it to good use on a project where I needed to see some high speed( ~500MHz) transitions clearly. I was using a 2465B for this until I got the 754C; being able to catch glitches and non-repetitive anomalies has already helped me out tremendously!

I beg to differ. Those shuttered LCD/CRT displays always gave me a headache so I replaced them with TFT. Still technology wise it is the only way to get color CRT without convergence problems.

Recently I bought a Fluke 25 in a ebay auction for 35€. Some digits on the display where dim, but that was due to a dirty zebra strip. After cleaning, the display is now good. I also had to check the range switch, because it didn't make contact on some ranges. I fixed that to easily.

I did already get it running.

Its in fairly good condition apart from one of the cables being cracked at one of the connectors. Haven't taken the lid off yet but i will probably have to since the grid on the display looks pretty fuzzy and a bit bright compared to the rest of the image. And damn is the thing loud so i might retrofit a quieter fan in it.

You can laugh now, but one of the reasons I go to the gym two to three times a week is to have the necessary arm strength for this kind of shite. Being able to turn over a DPO 40 times when fixing an error, or being able to balance a lecroy while a helper connects it to a short GPIB cable in the rack can be worth it.

Oh, and forgot to add: nice catch!!!!

Speaking of medical carts...

About 6 or 7 years ago, I was managing my parent's business after they retired. It was a pallet recycling operation. We got a lot of our pallets from these guys who would basically drive around in pickup trucks with a little trailer or small flat beds and collect the pallets from local businesses, maybe 20 or 30 a week. Anyway, these guys would come in sometimes with *amazing* dumpster finds.

So, one of the guys brought us pallets he collected from the local hospital. One day he had one of those big medical carts on the back of his truck. The kind with all the drawers and the big flat top, the huge rubber castor wheels; constructed out of rugged plastic, rubber, fiberglass and metal... Sort of like the one below, only with more (but not quite as tall) drawers on the right hand side.

Apparently, they were upgrading to newer carts on that floor and were just trashing the old ones! He ended up giving me two of them. They make *amazing* tool carts for a shop or garage! I left one at the pallet plant (for fixing stuff around the shop) and took the other one home. Used it until I moved for fixing my car and bike (it was fantastic, because I kept it loaded up with pretty much any tool you'd need to work on a vehicle, and it had that flat top so you could work on parts and stuff).

(http://uploads.tapatalk-cdn.com/20160809/76e3bed89cfb17d92152145d8c647a7f.jpg)

When I moved, I put it in storage. I should dig it out, as it'd make an awesome lab cart.

I wonder what the cheapest 1GHz source with sufficient fidelity would be?

A friend with a signal generator - maybe there is someone local to you on the blog that can help you out.

So, I found a SG 504 on eBay for $800, which is sort of insane. I put in a lowball offer of $70, since it's untested and doesn't include the leveling head. I ended up getting it for $100 shipped!

There's a guy on eBay who's selling homemade (but calibrated) leveling heads for $120. Apparently they provide better accuracy (0.1%) than the original Tektronix versions!

That said, I found a guy in the UK who came up with the parts list, schematic and layout for a DIY version, so I'll try that route first I think.

Either way I'm happy. Combined with my SG 503 I can now produce leveled sine waves from 50kHz to 1GHz at a voltage range of 5mV to 5.5V-PP!

Wow now that is indeed a steal.

A cheap way of getting fast signals are also some of these USB powered synthesizers. They are basicaly just a PLL based synthesizer IC with some RF amplifiers and attenuators on it. They go to a few GHz and some are calibrated at manufacture to a flat response, but the spectral purity is crap as it has tons of harmonics, but phase noise might not be all that bad.

About 6 months ago I picked up this HP 5385A Frequency Counter. The owner said it was blowing fuses. I finally had some time this weekend so I decided to take a look at it and see if I can fix it.

(http://i.imgur.com/GjhuxFX.jpg)

Armed with the service manual I dug into it.

Main board: (http://i.imgur.com/O0JPQ9e.jpg)

The cover actually has a battery and the battery charger as part of the included options (oven controlled oscillator was the other): (http://i.imgur.com/KbBb3f6.jpg)

PWM DC-DC +5V main rail regulator section: (http://i.imgur.com/VbH41sS.jpg)

Probed around for obvious shorted capacitors or similar and found no issues. The fuse was the only thing that needed a replacement: (http://i.imgur.com/NC3pxDa.jpg)

So I decided to disconnect the battery charger/battery module replace the fuse and give it a spin.

The instrument came alive, thermal camera also didn't detect any overly stressed parts: (http://i.imgur.com/wffrksS.jpg)

The issue is probably related to the battery option, which I don't care about. So I will just remove the battery and remove the option.

I am currently not able to test 100Mhz + RF frequencies (I have just scored an RF Sig Gen as well, but it's not here yet) but at least the sub 100Mhz frequencies seem fine.

2. HP 8591E Spectrum Analyzer, $200. Needed a new CRT. Found the entire unit on ebay for $50 (New). Passes confidence test, works well.

Yes, they were sold for parts or needs repair.

FYI if anyone needs a new display module for the 8590 series of SA. Here is a ebay listing for the one I bought.

Scored a HP 66000A MPS Mainframe with modules for 150US$ + shipping:

The seller stated that the modules are not working, but it turned out that the modules are not dead - they where just all configured with the DIP switches either in calibration or in Production only mode. Turning back the switches recovered most of them but one. That one had just a disconnected display cable :)

The mainframe itself did not work with keyboard connected. I've started looking for the problem, and figured out that one of the PALCE16V8 wasn't working. That PAL did some clock dividing to provide different clock signals for various stuff. Looked into my old box with all the EPROMs and such stuff from the 90s, and found a PEEL18CV8. Not exactly the same, but after installing Software to generate bitstreams for those devices, i got it running again. That was probably the first time i worked with PAL/GAL stuff since the 90's ;)

Nothing like that, I don't know of any hacks for it. I bought it to re-sell. Figure I'll make $500 or so. Current MSRP is about $7K. Crazy.

It has to be device that is an industry standard for measuring something esoteric that you need to either repair/buy another one if it smokes or rebuild and recertify your whole test setup and redo all paperwork, spending stupid amount of money.

It happens, and that's why for example you can still buy brand new 25 MHz generic TV-repair era analog scopes from some companies (eg Voltcraft) for pretty hefty price. Or analog meters (in microwave ovens industry procedures still call for AVOmeter rated for 2500V RMS to measure secondary of transformer...).

So here's the 8753C that came with a blown A sampler mentioned in the 8753C repair thread, shown doing an S11 measurement using a 11667A power splitter and Mini Circuits directional coupler.  Kirkby Microwave female calibration standards are on the left.

[Yes, I know there is something wrong with this picture, but note that vertical scale is 1dB/div.  I'm still working out why...]

Late night surfing found another ebay deal.
Got five Tektronix P6139A 500 MHz probes, three Agilent 10074C probes and one 1160A(this one is parts only) for $55.00.
All of the probes work, about half of them are complete with ground clips and hooks.

the P6139A's are a great match for my TDS7104.

Yep, they are quite nice and seem to the later generation that are black. I was also able to use the Agilent 1160A as I already had a complete 1160A probe kit and they include a spare probe tip and sleeve.

TEK 222. While not a real score (for the price I paid) it is in excellent condition, had the manual and the carry bag
When the Tek 200 series came out I was a young teenager and I was blown away by the small size. Was missing the earth clip (uses 2mm banana - so easy fix)  and had both probes. Dead battery (the weird 8V SLA - unobtanium) but will put some 18650 Li Ions holders in for portable use, if needed.

About 6 months ago I picked up this HP 5385A Frequency Counter. The owner said it was blowing fuses. I finally had some time this weekend so I decided to take a look at it and see if I can fix it.

(http://i.imgur.com/GjhuxFX.jpg)

Armed with the service manual I dug into it.

Main board: (http://i.imgur.com/O0JPQ9e.jpg)

The cover actually has a battery and the battery charger as part of the included options (oven controlled oscillator was the other): (http://i.imgur.com/KbBb3f6.jpg)

PWM DC-DC +5V main rail regulator section: (http://i.imgur.com/VbH41sS.jpg)

Probed around for obvious shorted capacitors or similar and found no issues. The fuse was the only thing that needed a replacement: (http://i.imgur.com/NC3pxDa.jpg)

So I decided to disconnect the battery charger/battery module replace the fuse and give it a spin.

The instrument came alive, thermal camera also didn't detect any overly stressed parts: (http://i.imgur.com/wffrksS.jpg)

The issue is probably related to the battery option, which I don't care about. So I will just remove the battery and remove the option.

I am currently not able to test 100Mhz + RF frequencies (I have just scored an RF Sig Gen as well, but it's not here yet) but at least the sub 100Mhz frequencies seem fine.

(http://i.imgur.com/klJDrJ0.jpg)
Not bad for $50.

$50 is a total steal. I think I paid $200 for mine. Nice photos, and troubleshooting.

Oh, they're cute.

I may be talking BS but check out the Hawker Energy Cyclon cells, they can be very handy if you're putting together a pack which needs non standard multiples of 2V cells and don't want to mess around with LiIon cells

The hospital I work at puts out surplus equipment (no electronics  :( ) for auction that few people bid on. I saw these after the action ended so got them for 1/2 the minimum bid.  Total paid : $7.50.     $2.50 for a high quality chair for my bench and $5.00 for an awesome modular equipment cart with a smoke evacuation unit that was attached to it.  The smoke evacuator works great!  Overkill for solder fumes but not sure what else to do with it :-//.    "Breathing laser smoke is a smoke hazard" but alas, no lasers in my lab.

Only problem now is that it is showing there is a 40/50uV difference with my Thurlby 1905a 5.5 digit multimeter  >:(
Now, I am going to have to figure out which one is correct or pay for a calibration  :palm:

That was quite an amazing deal there.

I had a planed to sell my MSO6034A (non X) when i got my next scope as they seam to still be worth a decent amount. I never got around to it, but then later realized it still gets used quite often so im keeping it.

Powered up and the front panel works perfectly, the 'screen burn', well, yeah, it wasn't. Ten minute teardown and a little bit of careful cleaning produced a lovely clean trace, good brightness, focus is a little soft but I think it may improve with warm up.

Now all I have to do is work out how the RF gaskets fit back in after they fell out onto the floor.

I have buyed one from france for a pay of€ 130,- +20 postage.
It got 4 pcs of this enersys cyclon cells, for around 40,-
so the little Tek is done for 190,-€ . This is a normally price for this collecting scopes,
also the other little Tek ( 211, 212, 213, 214, 221, and the little DSO 224, are still expensive. But take a look in the old catalogs to see how many $$$ was gone to get one, it is still OK  :)

Hi group,

Here is a picture of my latest 'score':

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251503;image)

It is a Fluke 187 that looks like it has been run over by car.

Here is a picture of the backside:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251505;image)

And the inside of the top:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251507;image)

I was given this to me free by a friend.

What is so great about this?

Well, I have another Fluke 187 that had a good case but had been exposed to a severe overload and was unrepairable:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251509;image)

I took the PCB assembly from the 'roadkill' unit and put it in the electrically damaged unit and I have a working Fluke 187:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251511;image)

Have you tried repairing the input protection section?  It would probably only take 5 minutes to check all varistors, PTC (half blown off), fusbile resistor (obviously fried), etc.

It would be similar to this Brymen BM869, but ended up being repairable.

Retiredcaps,

I had tried to repair the damage Fluke 187, It was damaged beyond the input protection circuitry. I cannot remember exactly what I tried. I had given up on it and I was keeping the damaged unit for parts. Anyway the 'roadkill' unit came with a good pcb, so it made the repair really easy.

The plastic LCD display bracket and case was badly damaged in the 'roadkill' unit, so apart from academic interest there is little point in repair the burnt board.

Good deal on the Fluke 187 donor guts!

There was a 'cost' I spent several hours repairing an HP6010A power supply for my friend.

This is how the 6010A looked inside:
(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251513;image)

The cover didn't look too bad.

But, under the cover:

Giant 'dust bunnies':

This was the cause of the problem, a damaged 10turn potentiometer:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251521;image)

After cleaning:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=251523;image)

I took the unit apart, washed the board in a sink warm water and dish soap. I washed the case and main board with a power washer and left everything to dry in the sun.

I also noticed it should be under warranty - as long as it is a standard failure and not as a result of someone trying to hack it. I assume it is flash corruption though.

An Agilent DSO-X 2014A for $460. It's still under factory warranty till 2018!  :-DD :-+

And you would have paid much less if I wasn't bidding against you! :)
I also noticed it should be under warranty - as long as it is a standard failure and not as a result of someone trying to hack it. I assume it is flash corruption though.

Damn you! (Of course you know, this means war!)  ;)
I didn't even want to post this one till it was in my hot little hands. It just arrived today, and I've already got an RMA # from Keysight. Ships out tomorrow.

I bet the seller would sh*t if he only knew.

Of course it means war, lol. I had big plans for that scope. I wanted to use it to experiment with jtag and the uboot boot loader in the 2000/3000 series scopes so we could fix them ourselves. Then it would have been time to try to up the sample rate and expand bandwidth to 500 MHz. So should Keysight refuse to fix it let me know.

I had always understood (based on what I've seen online, and of course can't find anything while searching now) that the serial number prefix indicated the year and production run. The first digit (3 number prefix) or two digits (4 number prefix) denoted the year when added to 1960 - three digit prefixes ran up to 1969, then they became four digit, and the latter two digits indicated either the week or production run number (there are some that are higher than 52) which would make your 5249XXX numbered instrument a late 2012 production (49th run, or 49th week) unit.  The warranty beginning in spring of 2013 would make sense as it may have taken a few months to go through distribution and make it to the customer, at which point the warranty clock started ticking.

My understanding is that 1960 is when they switched to the 'new' two part serial numbering system.

Just picked this up from the local fleaBay.
A 1984 Fluke 8050A, newest part was the chipset form week 11, 1984.
Just 11 years past calibration.

Now to clean it up, and give it the LED display mod.

Correct, you add 1960 to the first two of four digits in the serial number. The scheme is described in many of the HP user guides or operating manuals.

Wooohooo

Picked up Royel Soldering station RE900-4 for $42 Aus, fleabay.   Used to use these in Avionics repair F18 and F111.   OS members might not know "Royel" but they were one of the few "MIL Spec" systems made back in mid 80's.  When Australian F111s went to dumps (~2013) they were selling for around $800 on fleabay...thus this is a bargain.  Their new units cost...way too much for me.   I had 3 Royel Irons and even a Royel de-solder iron that fit this perfectly.  Just had to re-configure the pins as I was using them on a an old Adcola dual station and had modified the plugs to DIN...as everyone else had.

The de-solder pump...way over spec'd as well as resistance tweezers and dual concurrent irons... :-+ Winning!

Post by: wasyoungonce on September 20, 2016, 08:31:41 am
Yes...me thinks they seriously over spec'd the pump.  You only tun it with the foot switch for short bursts...seconds at best.  I did have my own vac de-solder set-up with a 12V fleabay motor, which worked ok, but is now consigned to the parts locker. 

I'm keen to get some resistance tweezers.   I'd make my own but I think I need something like titanium tips.  Not sure, need to research this.

Amazing what you can get from fleabay but it was probably useless without the irons....although there's no stopping someone making their own iron controller using their own irons.  The station uses a 30V transformer thru an SCR.

I've been trying to 'score' something for a while now, the target was a spectrum analyser and I had been chatting to someone about trading some gear for one and had also considered building my own but eBay came to the rescue with a sold as seen, faulty CMU200 for £154...

One flex of the credit card later and it was on its way.

https://s19.postimg.org/zd55dzrcz/2016_09_29_18_11_45.jpg

The reported faults were disk error, no boot and dim screen. Unfortunately it's arrived with a bit of transit damage, one corner of the front has taken a knock, but it's in good condition otherwise.

Repair consisted of reseating the IDE cable (after buying a replacement disk that wasn't needed) and the dim display I think needs a CCFL tube or and LED replacement, the CMOS backup battery also needs replacing.

Nice, thank you, I was thinking about using one recycled from a laptop (I have been harvesting them whenever I replace a smashed screen) but they're all rather long, I will have a look into modifying one.

The ones I used had three LED's wired in series, then each set is connected in parallel. They could be snapped apart at the end of each series string to adjust length.

That's in beautiful condition, especially considering that it's about 25 years old.  HP made some really nice test gear back in the day. 

Tough call on the board layout, though I think I'd lean more towards computer generated (by this I mean that though the arrangement and layout may have been done manually, the traces were then drawn on the computer with a layout tool) as they are very uniform and the angles look quite precise.  My older HP stuff that I'm certain was done with vellum and tape or something similarly manual have flowing traces that show slight width variations and don't always hit the lands precisely - they definitely look hand made. 

FWIW

I would put a vote in for computer generated on the 3312, I looked in the background photo of your  haul, your 5245L reminded me my repair, the heater oscillator board in the 5245L was definitely hand drawn.
Gear like that will last a very long time, good manuals, no crazy ICs. Often the specs are fantastic as well.  :-+

Heh! The first thing I saw when opening the thread today was your picture with the two regulators, and I immediately thought "that's a 3312A!". They are very nice generators, and the triggered burst with variable phase capability is something even most AWGs have difficulty with. Problems I had with mine were a failed PNP in the burst circuit (can't remember the exact reference designator) and the infamous exploding mains inlet filter - fortunately no harm done. Mine was also missing the power on pilot LED, suggesting it had spent part of its life in an optics lab. Enjoy!

Next up is a Panasonic VP-7722A audio analyzer. I'm kinda sorta into audiophoolery and I had no idea Panasonic used to make these things until recently! It's actually quite a respectable performer too, 0.00025% THD+N 2.5V @ 1kHz, 30kHz BW. It weighs a bloody ton at 17kg, might need to start a new thread for a proper teardown if anyone is interested.

I'm super impressed by the unit, because while it won't spit out pretty FFT's which are all the rage these days, I think it will be very handy for quick and dirty production line testing since you don't need a computer to operate it. It will happily dance with 'entry level' Audio-Precision analysers, I think you need an AP 2722 ($10k+ used) to better it in terms of THD+N anyway.


Any chance you have a manual or a link for the manual for the VP-7722A?

Well it took awhile, but I finally got an original HP 8698B RF plug in manual for a reasonable price.

Those clowns on that auction site are pretty proud of their manuals.

In any case, the 8690B sweep oscillator manual doesn't disclose the various disabled functions when certain plug-ins are used, i.e., the "standby/RF" switching in the oscillator doesn't apply with the 8698B plug in. Good to know because I was worried that there was something that needed to be fixed.

Not test equipment, but I'm pretty stoked with this. Yesterday I went to Flemington Markets and MSY in Auburn, for assorted small things. Near the markets I found a street-tossed office machine - a really big one on a pedestal.  It's a Canon imageRUNNER 2220i
Brochure: http://csscanon.com/uploads/IR2220series.pdf (http://csscanon.com/uploads/IR2220series.pdf)

Fortunately I had my son with me, since it took two of us to lift it into the car. Ha, the manual insists it's a 4-person lift. Weigh:   214lb. (97.4kg)
I'd thought it would just be something fun to tear down. It had no damage but appeared to have been left in a warehouse exposed to diesel truck exhaust for some time - lots of black grime. So presumably not working.

But no! After a quick clean it powered up, with a self-diagnostic fatal error code. Which, on downloading the service manual, turned out to be 'toner waste container full'. Emptied that (not accessible to users) and it boots up (from internal hard disk) and works. Operation logs in memory say it was last used in 2013.

So now I have a high volume A3-sheet laser network printer, scanner and photocopier. The user interface is a relatively large color touch screen. Nice.  Also the pedestal cupboard contained a never-used CD of the related graphics utilities.

This goes nicely with the perfectly working 'enterprise quality' A4 color laser printer I also found as a street toss recently. http://everist.org/NobLog/20151112_planning_vacuum.htm#printer (http://everist.org/NobLog/20151112_planning_vacuum.htm#printer)
That one got me out of a high-cost parking fine soon after, since the judge was so relieved to see a nicely printed 'why it wasn't my fault' presentation after all the shitty hand written notes he'd been reading for hours, he dropped the fine.
I wonder what this printer will be useful for?

I wonder what this printer will be useful for?
Do I sense a printed manual service ?
 :popcorn:

Now for a cheap source of paper......

Ha ha, no. I should post this in the 'products you hate' thread, but thermal toner books of any kind, I loathe them. Because the toner becomes softened and tacky with any diffusion through the paper of the plasticiser volatiles from PVC. Such as ring binder covers.
Result: With almost all photocopied manuals, after a while the first few pages at both ends start sticking to each other, and transferring the toner. Horrible.

Real ink on acid-free paper, it's the only way to mass produce long lasting documents cheaply.

Fortunately I had my son with me, since it took two of us to lift it into the car. Ha, the manual insists it's a 4-person lift. Weigh:   214lb. (97.4kg)

Joy of these office photocopy thingies. At my former workplace I had few outdated units gathering dust for years in strange places - at least three e-waste companies said they were "very busy" after hearing over the phone what do we want them to pick up. Also, fact that only two male workers were me and 6x years old electrician certainly didn't help with getting rid of them. I'm sure these copiers still silently wait for their demise at yet another unused corridor till this day:)

Tek 7612D digitizer with two 7A16Ps for free.

Playing with GPIB at the moment, the 1979 implementation is quite allergic to a modern prologix adapater. An old win 98 PC with NI adapter and software is able to talk to it. Strange thing with EZGPIB, it only works after using the NI "talk to instrument" feature first.

I also found old software online that is supposed to be able to take measurements. It's running on HP BASIC, so now i'm looking for a way to run this on Windows/dos.

Another challenge is to read the MCM6832 ROMs in the 7A16P's. My acient programmers are not old enough to handle them. The 7612D uses 2716, i did those (copied to KO4BB).

The mainframe seems ok. No errors when querying ERR? on GPIB. I'm also missing a real XYZ monitor

The best steel I have ever got and will ever get.
Two fluke 87 (original) just dusted them and working perfectly
One BK precision 60v/3A power supply
A few cheap clamp meters
Two voltage testers (I think good quality)
Two pipe bender things(He gave them to me I didn't need them)
All of this for $100.

Hands down I think I got the jackpot

This was unexpected. I think it's the first time I've ever found any professional high-end test gear as a street toss.
Recently I've been driving around more than usual due to visiting my mum in hospital frequently. This thing was sitting on a kerb on my usual route there yesterday, with some other assorted junk.

It's a Tektronix TG700 TV Signal Generator Platform.
Info: http://www.tek.com/datasheet/sync-pulse-generator/tg700 (http://www.tek.com/datasheet/sync-pulse-generator/tg700)
Loaded modules:
  AG7   6x50 BNC   Digital Audio gen
  DVG7  2x75 BNC   Digital video generator
  BG7   4x75 BNC   Analog black gen (opt CB for color bars - does not have, dammit.)
  AGL7  6x75 BNC   Analog genlock

All my exposure to professional video was in the '80s, so analog video only. This thing is mostly digital video, so quite interesting. It seems to be completely working (its self-check claims) though as yet I don't have any other digital video gear.
When I first started playing with it (before I had the manuals and list of module functions) I thought one module was broken since the menu said it was generating color bars, but all my bench scope could see was HF white noise. Ha ha, it's a digital video stream.
It was dirty and stickered, but cleaned up nicely. Even had the protective film still on the display.
Oh, and miraculous wonder: the rack slide rails are complete. How often does *that* ever happen?

Last 2 pics: At the other far end of the tech-spectrum, in the same pile was a tub of tools that had been left in the rain. Cleaning these up is kind of an obligation to the fight against entropy. Just light surface rust.

I spoke with the people at the house; they are 'clearing out the house for a friend'. Huge piles of stuff already moved out in the yard. Arranged to go back and meet again tonight, to see if there's anything more like the Tek.

Thanks. I'm considering it unlikely - probably that was just something the resident had acquired and didn't know what it was. Mostly I'm just curious to find out the history of how it came to be there. At the time I was speaking to an old Asian lady with no English, via a young girl with not-so-great Vietnamese Cantonese. The guy who knew stuff wasn't there.
But you never know.

No really, when I said "light surface rust" I meant it. All clean now, see pic. Only the two feeler gauge sets were far gone, and even they will do as car-kit.

Large diameter steel wire wheel in a bench grinder for most of it. Some concave bits with stainless steel wool hand scrubbing. The files and delicate things like the teeth of the taps, with fine brass wire brush and running water. Then a light coat of oil on everything.

Mainly I wanted the chisels, of which I don't have many already. Everything else was just 'well since I'm doing this, why not?'

Bought a HP 8903A Audio Analyzer, posted working but arrived with no working display despite being reasonably well packed, "grace03us" sent a good sized part refund on my word alone!
Opened the lid and after a bit of digging around fixing the 1980s HP "clacky button problem" found a loose cable- plugged it back in and she lives.  :-+

That's a vintage tube tester! I am looking for simmilar devices for years but wasn't lucky at all, since they always end at a (at least for me) unaffordable price... The questionmark in the meter was to show the transit area in which a tube would work as expected but eventually with reduced power, since theose things most of the time measure just the current going through the tube at the standard datasheet values. You could say that a "?" tube is most of the time perfectly useable, as long as you don't try to squeeze every last µA out of the cathode.

Valve testers are handy if you have a lot of valves/tubes to test or have unskilled labour that needs to qualify them as good/bad but it's not particularly difficult to test valves without a custom tester, just needs some fairly basic lab gear and some common sense regarding electrical safety.

Tube testers are reasonably good at determining if a tube is dead or shorted.  Whether the tube is actually good or usable is another story.  They were also not laboratory instruments and their primary role was to help service techs sell tubes.  The best way to determine the actual characteristics of a tube is to use a curve tracer.  Tektronix actually made one, the 570, but the audiofools have priced these into the stratosphere (one sold for $2K on ebay back in Sept).

There's at least one modern computer controlled tube curve tracer available and it's fairly easy to use a Tek 576 with some additional setup.

Re tubes and testing, when I was restoring my Tek 545 (all 107 tubes I recall!) i got a uTracer3+ from DOS 4 ever, it is a proper tube tracer but has some nice features in that it doesn't test the tube for long at each voltage so you don't have to get too excited re power limits etc. As the HV is only around for a short time (I recall some milliseconds) your chances of 'exciting' yourself also goes down. The biggest issue is you have to build it and get the tube sockets you want. It is basically a computer controlled 3 power supply (2HV,  one for filaments) and 2 voltmeter 2 ammeter unit with a nice PC interface to drive it all.
PS No interest other than a happy customer.

I always feel I should pay the price agreed at the deal unless it is not as promised, I was a little bit upset when it arrived and it didn't work and sent off a polite  email and he was nice about it. The postage to return it would have been a killer , the seller was happy to strike a fair part refund and when it turned out to be a simple cable issue, perhaps it spent a lot of the trip upside down. I too want to encourage the good sellers with a fair deal.

I seen someone take a wire wheel to files and then dunk them in acid for a bit to restore and "sharpen" them. But im not sure why would that work, but if anything it would get the crap out of the groves so it can dig in properly. Etching it should round and dull the teeth if you ask me.

I am almost certain that acid "sharpening" is a myth.

That's my thought as well - it would seem that the 'finer' features (such as sharp cutting edges) would be the FIRST thing that the acid would etch away, rounding and dulling them as the post above yours suggests.  Seems like a good way to TRASH a file, rather than sharpening it.  If you can put it into something that would dissolve whatever swarf is trapped in the grooves and NOT the file, that could clean it out well and potentially make it cut better if it's clogged up, but I fail to see how something like that could sharpen it at all.

To derust simply use a wire brush, hand held, and brush parallel to the teeth. On a crosscut file you need 2 passes, to get both angles of the teeth, then wash with some kerosene ( paraffin in the rest of the world) to clean the debris out. Then after that use a cloth dampened with light mineral oil to rub off all the remaining rust, and store where it will be dry. A wooden drawer that has bare wood, oiled with furniture oil, works best as a rust preventer, as the volatile oil compounds evaporate over the tools with time. You can buy corrosion protector tabs that are basically an oil soaked sponge that do the same.

Definitely, from what I remember using a brass brush on a file is a pretty good way to wreck it and if my metalwork (shop?) teacher caught us using anything other than the card brush we would be given a stern lecture about how not to destroy his files. (filing aluminium without using a lubricant was also a fairly dangerous thing to risk getting caught doing)

(filing aluminium without using a lubricant was also a fairly dangerous thing to risk getting caught doing)

I'm amazed at the things people say & believe sometimes.
Please explain how soft, fine brass wire tips are going to damage the high-carbon steel of a file? Considering that the file can cut into solid brass all day and not get blunt.
As opposed to the hardened spring steel of any kind of steel wire brush. You _can_ use a steel wire brush, if you're careful to only run parallel to the file grooves. Which you do if you're trying to remove stuck swarf. Go the other way and you might as well file hardened steel (ie throw the file away, because you just ruined it.)
The card brush is useful because the bristles are both short and mounted in a flexible base sheet that allows them to tilt. So it's a way to apply a stiff but limited force to stuck swarf. But I don't bother with them - just one more rarely used special tool I can do without.

Personally to clean files I never use anything but soft brass wire brushes, and kerosene as a releasing/penetrating lubricant (because it's cheaper than WD40.) If some metal has stubbornly stuck, then run the tip of a scriber along the file grooves that need cleaning.

Removing surface rust is a different problem to stuck swarf, since it's all over all surfaces. Needed some scrubbing across the grooves too, so definitely only with a brush much softer than the steel.

Actually it was surprising. I don't know what wear-state the files were in before they were left to rust in a tub of rainwater for a while. But after scrubbing the rust off (and high-carbon steel seems to rust less than other steels) the files were all very sharp, like near new. Maybe a little rusting is similar to the acid-etch sharpening method?

And though I've never tried acid-etch (keep meaning too), I don't know why some people can't see how it would work. The solution doesn't preferentially eat corners, it takes off _surface_. So, think of a triangular point, but with the point slightly rounded. Now remove a little of all surfaces. Yes, it reduces the radius of the rounded bit, and can re-create a sharp point.

Btw, I had some more contact with the people who tossed that Tektronix digital video gen. And did score some other assorted bits and pieces, more on that later. But the answer to the mystery is that the owner was a hoarder, the Tek was something he bought at an auction, and no he didn't have the rest of an editing suite to go with it. Which was a great relief in a way, since the first person I spoke to with good English mentioned they'd already sent piles of stuff to recycling, and I was getting pretty depressed wondering if some really nice things had been scrapped. Still wish I'd seen the house though. Always satisfying to see a _worse_ hoarder's pile than my own.

I was lead believe it's because the brass can clog the teeth on fine files rather than blunting them and that, I would assume, would also depend on the type of brass alloy used.

Your use of kerosene as a lubricant may also negate the effect entirely.

I just know that a card brush didn't require the use of lubricants to clean a file, as such it seemed sensible to use one when cleaning a file.

I just got a TDS220 from my favorite dumpster.

When I powered it,  the screen  was  dark, but I noticed that it  was working. obviously,  the CCFL tube was dead.
I checked the power supply that looked OK, and ordered a CCFL on aliexpress.
The best deal I found was 10 for 16 € ( in fact I received 11, so its less than 1.5 € each).

I have changed now the CCFL. Many plastic parts were very brittle, and I had to  use some Kapton tape for remounting,
but everything is now fine and in working order.

So the total cost of the repair was 1.5€.

I have already several other scopes, including a recent Rigol1054z (the only one that I had to pay for),
but I like the TDS220.
It has roughly the same form factor as the Rigol, and same bandwidth (100 Mhz). Of course, it has not
as many features, and is only 2 channels.
But it has a huge advantage :

It is totally silent !

I was really looking for such a scope. It is very enjoyable when you are in a quiet atmosphere,  not to have  the fan noise
of some modern devices.
In fact, my old fashion power supplies (coming straight from the dumpster) are linear PSU and also totally silent, contrary
to many new SMPS that usually need a fan.

I am sure that the evolution will go towards fanless devices, as it is now for many  laptops,  but  makers are probably still
thinking that a lab is a noisy atmosphere, so additional noise is not a problem, and they prefer to increase the performances,
without considering the noise level.  I am sure this will change. Meanwhile, its nice to have some of the old,
not so performant but silent stuff.

They use a discrete push pull oscillator on the backlight inverter primary and the dipped ceramic cap for it measured pF's.  :scared:

That's all that was wrong with it.  :)

Getting a bunch of those drivers is probably a good idea given how much test equipment with LCDs uses them for backlights. Even brand new equipment made today seams to use them on larger displays.

I also think too much equipment has fans, ridiculously loud ones sometimes even. My lab tends to be pretty quiet as the PC in there is fitted with quality fans and set up for speed control so as a result the PC is so quiet i don't even hear its on unless one of the mechanical harddrives are spinning. Turning on a piece of equipment with a loud fan in there makes it seam like a jet engine just started up. I tend to replace loud fans in equipment, but that's not always possible. For example my HP 8566 gets pretty hot even with the loud hurricane creating fan blowing trough it

Yesterday I managed to 'win' an Ebay auction for an Agilent N3305A 150V/60A 500W electronic load module listed 'for parts'.
(http://www.uspowerandtest.com/wp-content/uploads/2015/04/102_0418.jpg)
This is supposed to go into a DC load mainframe which I already have (bought from a forum member) and it came up just in time because I have a project coming up where it will be usefull. I have been angling for one of these modules for years on Ebay and now I got one. Unfortunately it was an auction so I put in a bid a couple of hours before the end and just see where it goes. Much to my surprise the price stayed well below my bid at US$56 and only one 'sniper'. Still I can do without the excitement though.

If it does not immediately work....hopefully an easy fix. I got a lot of Chroma DC modular loads in various condition. The broken parts have all been trivial - the circuits that do the heavy lifting are fairly difficult to damage. Good luck.

Recently someone was selling Fluke 27/fm meters on ebay for $15 US ea with free shipping.

Not guaranteed, no accessories and power on test only, but heck, $15?  I bought 2.  We'll see when they show up, but reports so far have been favorable.  They're worth it just for spare parts.

I'll probably regret not buying more.

Picked up an older Analogue Scope, Tektronix 2236, for $135 in Australia (Melb) this morning.  Purchased off Gumtree (like USA craigslist) so no fee's!   Found most people on fleabay (and Gumtree) wanted way too much but this was ok price.  Appears to be working A1 so far.   I'll do the PSU capacitors just to be sure!  Need to get a decent repair manual...the online A4 sized documents just don't cut it.

The guy purchased from is giving up TV/radio repairs.  Just no money in it these days and I tend to agree.   We had a good chat, nice to meet like folks.

The latest addition to my home lab. Measured on a freshly calibrated HP3458A shows the value of +5.5ppm from 10K, or less than +6ppm from the original measuremed value printed on the unit (which is in turn less than the uncertainty of the HP3458A measurement).

Cheers

No cheap DMM will measure 2 Gohm, I can assure you of that. And most won't have a low ohm range with 0.01 ohm resolution either. The 8-digit 100 MHz counter is also useful if you don't have something better on the bench.

Good point! I guess since I don't recall having yet had the need to measure resistance at either of those extremes, I hadn't considered that!   Cool - another justification for keeping it around! (Next time my wife asks why I need so many of those things..  ;D.)

Just noticed the the CTM is registering 957Hz with the probe on 1Khz probe adj.  Don't know if it's the CTM or the probe adj...probably the latter.

Exactly why you mustn't use the internal probe cal output to make ANY internal adjustment of a scope.
But some scopes have an internal frequency adjustment for the probe cal output and when they do it's handy to set it close to the spec'ed 1KHz even if it's only for sanity checks.  ;)

A quick update on the N3305A DC load module (150V / 60A / 500W) I bought recently. This is the photo from the actual Ebay listing:
(https://c2.staticflickr.com/6/5446/31262295241_605afe6073_z.jpg) (https://flic.kr/p/PCxrdn)

Unfortunately the module I received was banged up pretty bad. It was well packed and the box didn't show any damage so my guess is the seller must have used an image from somewhere else for the Ebay listing. After taking the rear shield off (including the binding posts) and straightening it I tested the module. It seemed the constant current mode worked just fine but it didn't read any voltage (remote/local sensing didn't make a difference).

A quick inspection showed several resistors placed in a string hinting towards some kind of voltage divider and they where near the 'impact zone' so I measured them. It appeared some where off so for good measure I replaced all the 100k Ohm ones (4 in total). Fortunately the schematics for these modules are available and it shows these resistors are 0.1% types.
(https://c1.staticflickr.com/6/5826/31008122680_a7e8691bdc_z.jpg) (https://flic.kr/p/Pf5JyQ)
I didn't take the module apart except for removing the two capacitors on the right to allow measuring the other resistors. After the repair the voltage readout worked again and it is spot on compared to my Agilent 4.5 digit DMM. I did some further testing (full load  >:D) and it seems the module is hard limited to 560W.

Got an oldie-but-goodie at a local ham club auction. An HP 410B VTVM for the opening bid of $1! 

Needed all new probe cables and a line cord (rubber was dry-rotted and crumbling), but the thing cleaned up beautifully, and the calibration was still pretty close after all these years. 

Replaced the electrolytic cap and a selenium rectifier just on general principles, and the thing calibrated in perfectly, with all the original HP-branded tubes still in it!

Really didn't NEED it, but does have an Rx1M range that reads up to 500 megohms, a DC input impedance of 100+ megs, and an AC voltage probe that works up to 700 MHz, exceeding the capabilities of my more modern gear.  Plus the AC probe (with internal tube) keeps your hands warm in the winter... 8)

Power Designs TW5005.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=276016)

$10 CAD at the local government surplus depot.

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=276018)

A friend of mine got one of these there two or three months ago and was quite pleased with it. I think his might have been the TW5005T version. I was envious from the moment I saw it. I don't think he knew the brand, though; I recognized it right away because it's popular on here.

This past Friday, I happened to look at the surplus seller's online list of things for sale (which is just a very brief description and occasionally a photo or two, no prices) and saw "precision millivolt source" and "twin power supply", so I decided to go over and have a look. I never found the millivolt source, which is what I mainly went for—it was probably bought between when I read the list and when I got there; it's no longer on the list today—but I did discover that the "dual power supply" was a way nicer one than I'd expected from that description. Strangely, they put power supplies from local brands nobody's heard of in the online auction section, where they fetch prices around $75–150, but Power Designs power supplies in the cash&carry section for $10!

It's remote-controllable, and it has a cord winder that the person who packed it up to sell apparently didn't notice:

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=276020)

There was also this note, held on by ancient masking tape that fell off when I picked it up, saying "RETURN ALL":

(https://www.eevblog.com/forum/testgear/list-your-test-equipment-score-here!/?action=dlattach;attach=276022)

I haven't taken it apart yet, let alone turned it on, but I did see some interesting stuff when I looked in through the vents (on the back, hidden above the resistor house in the third photo) using another score, my new endoscope (http://www.banggood.com/AN102-0_5M-3M-8_0mm-Lens-720P-Handheld-IP67-Endoscope-Android-PC-USB-Inspection-Tube-Camera-p-1052696.html), which I got for $15 CAD ($11.11 USD) on 11/11.

It gets even better.
The triax on the 619 are old style (2-prong) leaving you to use an old style cable (hard to find).  Alternatively you could get a 2-to-3 prong converter or upgrade the 619 bulkhead(s) to the modern 3-prong.
Did I mention there is also 2-prog triax to BNC converter - which loses some of the advantages of the triax topology but allows for a cheaper cable.

let the good times roll...

Speaking of triaxial cable, I needed a few feet of it for the restoration of the HP 410B mentioned a couple posts up. It is used for the AC probe cable, where the outermost shield is used to carry filament power to the probe diode. My probe cable was severely deteriorated and falling apart.

Not finding a convenient source of just a short length of raw triax cable (and not wanting to hack up a $$$ cable with connectors attached), I decided to try making my own. I found that Belden RG-174 cable (type 8216) is just about the same OD as the inner conductor insulation in their RG-58 cable (type 8240). I was able to solder a length of RG-174 (shield and center conductor together) to the inner conductor of the RG-58, and using a vise to hold the opposite end of the RG-58 center conductor, I was able to use the RG-58 center conductor to pull the RG-174 INTO the shield and outer jacket of the RG-58, creating a triaxial cable. The 174 serves as the center conductor and inner shield, with the outer shield from the RG-58 left over to serve as the filament power conductor as in the original HP cable. 

Probably wouldn't work for more than a few feet of cable, but this little hack saved me from trying to track down a short length of triax, or buy a full spool of the stuff for way too much money.

I've just found this handy looking device on Ebay AU and it's listed at buy now for $15.95, unfortunately it's also listed as pick up only and I'm in another state so that's out, if others think it might be of some value then I could probably contact the seller and perhaps work out a deal or somebody else here might be interested, I couldn't find any information on it via a Google search. Anyway, it's described as a Proteq Board Wizard Combi Test and I'm guessing that it might be a continuity tracer of some type, it does look pretty handy and ticks all the boxes.

I just got myself in to a worse triax nightmare. I bought a HP 4141B Source measure unit for 100 bucks and then found out it has 5 triax connectors on the back(4 SMU channels + 1 precision GND signal). Okay no biggie il just buy some cables for that, quick look online and.... they cost HOW much?! :o

I almost bought a bunch of new old stock triax connectors from a guy on ebay before i realized the connectors are 2 stud BNC while my HP boatanchor has 3 stud BNC style connectors. In the end i spent like 100 bucks again on buying 3 sets of long triax cables that i plan to cut up in the middle and put some more sensible connector on the end like XLR or something.

Well this HP 4141B seams to impossible to even buy a manual for if you wanted to. All i got online was one section of the programmers guide while for the rest a manual from a similar HP unit had to be used. No service manual what so ever to be found. This made it particularly scary when i first turned it on and the Fail LED came on, pressing the selftest button resulted in the same. Later on i found out that the high voltage interlock connector on the back needs to be shorted to GND for it to pass self test. Phew what a relief.

Another hidden cost i found is buying a >500MHz scope. Suddenly you need all new fancy pants active probes to make use of that bandwidth, and those things don't come cheep let me tell you (But then again its amazing how crisp of a signal they get, <1pF probe capacitance is a world changer).

Usual ball-park pricing for low-noise triax cables with 3-lug ports is 50-200$/pc :). You can get some connectors from Digikey (TRB type they call it), about 23$/pop, as cheap as they go (if not counting ebay gambles).
Also don't confuse them with twinax which look similar and use mechanically same connector, but very different in performance and purpose.

Perhaps my article on Agilent 4142B (https://xdevs.com/fix/a4142b/) could be useful for you, as it's similar box. If you plan teardown of 4141B, I'd love some photos! Wear non-coated gloves if you decide to peek into front end sections...

I bought three 4m long triax cables for 56 USD a piece, on there way from the US right now.

That is a interesting article you got there. I actually used the manual for the 4142B to get an idea of how these things work. And i couldn't resist taking off the lid when i got it because i was curious what was inside to make the thing so massive. To give you a sense of scale the whole unit is half a meter long (about 1ft6) and takes up 4U of rack. I expected it to be half empty inside but was i wrong. Interestingly it also has 3 "shield domains" inside where parts of the internal metal case are held separated by plastic spacers. The PSU has its own shield domain, CPU its own and the large analog section has its own. Enjoy the preliminary photos(Might make a dedicated forum thread for it since there is no info on them yet quite common on ebay.).

I have not pulled out any of the cards because when i first tried to they seamed to really not want to move. Pulled so hard that i was afraid of breaking the plastic tabs. Its possible the environment it was in had some volatile solvents floating in the air since the case feels a bit sticky and some less important looking cables inside felt really sticky. Its not like it got something poured on it because any metal work around the sticky cable was perfectly clean, not even dusty. I had a guess that maybe something similar happened to the backplane connectors to get the boards so stuck in. I need to have another go at it by dissembling it a bit more so that i can get a better grip on the boards. I need to do something about that loud fan at some point, tho i have no idea where to stick a fan speed control circuit with how full the insides of it are. Also need to find some software for it or write my own.

Front ends on these are well encased in metal cans from what i can see, but i would assume its very similar to your 4142B since this unit is designed for 100V 100mA just like your medium power modules. Id love to have a high current one in here too, but then again i did get it for just 100 bucks.

Glad to know I wasn't the only one swearing at the price of Triax, up until then I thought heliax/connectors were expensive.
I have managed to find some "2 lug" triax to triax  and 2 lug triax to croc clip cables, cost more than the Electrometer.  I think I will include them in my last will and testament!
I like the 'hack' of N2IXK with RG174 and the outer shield of RG58 :-+         Now to hack a connector somehow >:D     (not looking hopeful - but easier with the 2 Lug version)

I went the same route when I got my first Keithley Electrometer and could not believe my eyes when I saw the prices for cables and connectors.
Have you looked for a TRIAX T-Connector.
Don't be surprised at $400 each and up!
Then I learned to also look for "Trompeter" connectors and found many more for reasonable prices.

Picked up a repairable Tek 454A on a local craigslist sale for $30.  Guy said is was fine other then the "picture tube" [sic}.  Gotta love nontechies.  A quick look showed a crisped resistor on the regulator board and a blown LV fuse.  It won't be going into the "easiest repair ever" thread, but shouldn't be too difficult to bring back to life.

As a bonus, it was an IBM scope which is a neat piece of history.

Notice how most of the scores are from people in America, specifically USA.
its hard for us who live in a dirt-hole score an equipment on eBay without paying 200$ for shipping itself.

True but even then you can get better deals from the US then on a local market. Over a decade ago I paid $350 for shipping a logic analyser I won on Ebay for $66. Besides that you can also find nice deals from Asia. OTOH recently I missed out on some nice DC loads because shipping was just too cumbersome and the seller decided to sell to someone who picked them up.

Yeah its common to pay over 200 bucks to ship some big boatanchor piece of equipment from the US. But sometimes you find a deal so good that its worth it even with the shipping.

Another thing is that the seller has to know how to pack big heavy equipment properly. When not packed properly one decent drop of the box on the right corner can cause quite a bit of damage when the thing weighs like 20kg. When it has to get here from the US that makes it go trough more "nodes" where the post office gorillas throw the boxes from one vehicle to the next. And yes the term "throw" is the one to use judging by some of the shipping horrors that made it to my door.

Luckily the old gear tends to be made out of metal so a lot of the damage can be fixed by taking it apart and bending it back (Luckily damage on gear i bought was always just cosmetic).

In case anyone is wondering crumpled up newspaper is NOT fine for shipping a 30kg power supply overseas.

Yeah, for something that heavy you'd definitely want to step up to butcher paper as packing material.   ;)   :P

What some people consider to be adequate packing simply boggles my mind sometimes.  The Electro Instruments DVM I got from the 'bay a while back springs to mind.  It basically had NO packing - the guy folded up and hot glued corrugated cardboard around it.  (Though I suppose it could be argued that he made a custom box for it...   :palm: )

Few BNC accesories for my T&M stuffs, not the top tier brand though, but good enough and should be adequate for hobbyist use.

- Full metal BNC feed thru 50 Ohm termination, not sure it's capability at GHz range though, but my requirement < 100 Mhz should ok right ? So sick & tired of using separate BNC T connector + 50 Ohm terminator.

- Panel mount isolated BNC female connector, not sure when or where I'm going to use it  :-//, its the "isolated" feature made to grab few of them.  :palm:

- Right angle BNC male connectors, had been wanting these for quite a while, no more stressing those hanging short coax wires when used at T&M equipments.

Where abouts did you get the feedthroughs from and how much were they? My stuff only goes upto 10MHz for signal generators, or 100MHz for the scope, so I don't need anything rated to GHz either.

Aliexpress, just search for "P7001 BNC" , currently only one shop sells this, at least from my search.

Remember, I'm not affiliated with this shop, and priced at $8.55 for two pieces (free s/h).

I haven't throughly test it yet, but a quick DMM check they're spot on at 50 Ohm.

Have not had something packed quite that bad, hope it didn't get too beat up.

But looking at the other end of the spectrum i seen some amazing packing jobs. For example that SMU that just cost me a fortune in the stupid triax cables came packed in a huge box with the instapack foam bags all around it a good 15cm thick. Naturally the unit got here without a single scratch from shipping despite the box exterior looking like it got a good beating.

Having a look at the sellers ebay store can give you a hint about the packing to expect. If the store if full of large test gear and they have a reasonable ebay rating you can be sure they will pack it properly (They likely already learned the hard way the importance of packing heavy stuff). When the seller sells various little non technical nick nakcs expect your shiny new bit of gear to get a bit banged up. Something to keep in mind when buying a piece of gear in like new condition (Tho it sure was satisfying peeling the screen protection film off a Keithley 2015 DMM that i scored for cheep).

They are both in very good shape.  Installed a 9V battery and tested them out.  Everything works, very accurate, safety fuses intact. 
The vendor even did great job insta-packing the 2 units. 

Should have a couple of low cost Keithley 197's coming from the same vendor - Hopefully more good news.

Recently I acquired a HP 8616A signal generator for around 30€. It can be adjusted to frequencies between 1.8-4.5 GigaCycles (who uses Hz anyway?).
I retrofitted a IEC-C13 connector on the back, as I could not find a suitable cable for it. Probably I should also swap some of the electrolytic capacitors in it.
 
In the future I want to get more into RF stuff, so I will be looking for more gear like this  :-+

I picked this up for $79.00 (+$150 freight, taxes, etc)  8).  It was a gamble because I could make out in the out of focus picture that it had a Defective tag on it.  Upon arrival, I was able to read the tag: 200A Switch Bad.  It was up for Cal the previous month which it failed presumably due to the bad 200A switch which wouldn't stay latched. Where in the world was I going to find a replacement ganged switch??? I desoldered the switch assy. and got a number off one of the switches.  Individually in stock at Digikey for $2-3 each.  Upon closer inspection, the shaft of each switch was symmetrical so I simply flipped the locking plate and spring the other way round, put it back together, and I now have a fully functioning 600V / 400A / 4Kw DC load  ;D.

Sbampato12 - I am always amazed that you manage to find anything at all in our country. I constantly monitor the usual websites for test equipment and all sorts of things hoping to ever find a bargain / reasonable deal, but am never lucky! The few I came across in the last few years (like a wavetek sig gen) I wasn't able to land. The only piece of test equipment I ever bought used in Brazil was an Agilent E3634A power supply - the seller was clueless though and didn't pack it right, so it got broken in-transit. No worries, I managed to buy a replacement front panel but after a few weeks of light usage it died. I am yet to succeed in my repair attempts.

Bottom line - if you ever come across something you don't want, ping your fellow country man here  ;D

Accuracy as a decade resistor 0.01% +0.005. Which is interesting since it has a 0.001 ohm decade(2111.11 Ohms total) Those will be put to work in another project >:D.

Christmas came early for me. An elf dropped a package at my doorstep yesterday, containing a LeCroy WavePro 960 DSO. Four channels, 2 GHz, 16 GS/s, 16 MS memory. It has many options including Ethernet interface, PCCard slot, hard copy (built in printer), and various math/analysis features including WaveAnalyzer and WaveAnalyzer Pro for FFT, jitter analysis and more. It works perfectly, and the icing on the cake is that it was calibrated this past summer so it's still within traceable cal! I paid only $1200 USD plus shipping and taxes. Used LeCroy scopes are a tremendous value. Now I have something to use with my Tek P6158 3 GHz low-Z probes (which I scored for $5 each BTW). I'm way too busy today and tomorrow to really play with it, but I'm off for the next two weeks so I'll find time.

A PC card to compact flash adapter will allow a CF card to appear as Hard drive storage unit, which it does support. Floppy drive emulators are also available which allow storage to a disk image on a USB drive, but you are still limited to 1.44 MB at a time, a limitation that doesn't exist with the CF Option.

Another Stanford Research FS700 Loran Timing Generator !!! (4 now :palm:)
But!! This one was under $40 on the bbay , most are over $700  :-DD Local find, so picked up and saved the shipping. Stanford research is in Sunnyvale (Silicon Valley not far from here) They must have cleared out a bunch of cobweb equipment they didn't want to bother with. This thing never got Final Assembly. No case, ROM chip was removed (have some), no OCXO (had one of those too), no cables connected EVER, LCD Protective film still in place (they gave up). Powered it up, but got ERROR! Amplifier Gain too high/low. Found someone must have poked around in the LF353 chain of RF op-amps, and blew up U105. Replaced it, thinking I might be done. WRONG!!!
After much hunting for why the CAL signal did not seem to get amplified I was led to K101 relay, and found a pin that appeared soldered, but NO!!! it was NEVER soldered properly (it's in a dark corner of the board). Up and running now after a few hours playing around with this. These work great with Rubidium signal, or GPSDO signal instead of the LORAN/OCXO.

Sorry for the poor photos.

It is not in perfect condition but works well. Lenses are a bit scratched but I hardly notice when using it. It is missing transparent front glass and table mount part.

Got a Mantis Elite with arm, 8x and 15x lenses for GBP 150+GBP 50 shipping listed as for parts. (So about $240)

It is not in perfect condition but works well. Lenses are a bit scratched but I hardly notice when using it. It is missing transparent front glass and table mount part. But for that price I cannot complain. :) It could do with a clean of the internal glass at some point. But I'm not complaining at all.

Wow, that's a score alright. I guess all the parts were there. :-+

From last month's ITT Tech auction:
2 x GW Instek GOS-6112 Oscilloscopes
2 x GW Instek GDS-830 Oscilloscopes
2 x GW Instek GDS-2102 Oscilloscopes
2 x GW Instek GDM-8251A Bench Multimeters
3 x GW Instek GPD-3303S DC Power Supplies
23 x Rigol DS1102E Oscilloscopes
2 x Rigol DS1102D Oscilloscopes
3 x Rigol DG1022A Function/Arbitrary Waveform Generators

First real auction I've done and even though I did very well, I've got to admit it scared hell out of me. I liked it way too much. I was only hoping to get a couple things for myself and maybe some scopes to turn around and resell to recoup some of the cost. Now I've had to go and turn myself into a part-time used test equipment salesman  :palm:

Lol it was supposed to be 27! They could only find 25, but 2 of them ended up being the 1102d's

Yes - so just need a 4x lens and table mount. I did have a Mantis Compact so Elite fitted on my existing table mount. But the Elite gives a slightly larger image (Roughly 20% is I think)  - and the LEDs are slightly brighter - and you get slightly more usable work-space below the lens - plus easy change between 2 lenses.

So now the compact will go to the vacation home where I have a mini-lab. :)

I then picked up a set of replacement Left/Right LEDs for 39 Euro - new and unused on eBay - SRP about $240/Euro 220.

So now only table mount, transparent front and 4x lens and it is complete. But great score - SRP for the parts are around GBP 3000,- USD 3500,-

When I first entered the trade, I made a point of providing new probes and as much documentation as I could find and compiling it onto CD's and advertising the fact. They'll move well, good luck...new name TEnavigator.   :clap:

Yeah. Probes are cheap and for some reason potential scope buyers are always obsessed with probes.

Well.. that is generalising it quite a bit: garden variety Chinese probes might be cheap, but real ones are not (in general).

Hint:
Guess who makes the OEM probes for most Asian scopes....the same manufacturer that makes the "garden variety".  ;)

Haha, yes, it's easy to get carried away. It's just too fun. Ah, so those listings are yours. Cool.

I actually haven't listed anything yet. Been trying to pass on as many as I can locally. There are quite a few items from the same auction up on eBay right now. I got the largest lot of 1102e's from the 1st ITT Tech auction, but there were much larger lots at the last one. Seemed like many bidders were getting them for institutions. It was absolutely insane watching what some of this stuff went for. Some really good prices and then other items that people just bid through the roof. The spectrum analysers seemed to work everyone up in a frenzy to the point they continued bidding the same price per unit on some similar looking at a glance analog scopes. 2 hours later the same model scopes were going for $2 per unit. It was really depressing seeing the bidding on unused graduation caps & gowns. The craziest thing was seeing a lot of 18 pallets of textbooks go for over $12,000. From what I understand those books were ITT Tech specific and therefore worthless for resale.

Can you point out some links to these ITT Technical Institute Ebay auctions?

Note that I contacted the official auction site, but never got any response on my email.

Wow - I just looked. Lots of older but decent looking GW Instek scopes and power supplies. Many 100MHz scopes under $100 and triple output linear supplies under $50.  Not bad deals for a new hobbyist on a tight budget.

Just had a look and those GW Instek tripple power supplies look pretty nice actually. Not far off my Rigol DP832.

But i really have to stop buying powersuplies, i already almost ever use some of mine. :-\

I will be in the US next couple weeks and am interested in a function generator, in case you're selling any of them. PM me if you are, and the price. I will be in TX.

Hmmm.
I know of at least 2 probe Asian probe manufacturers, one of which makes a large range including actives and they are little known of. Despite this the make a large # for many scope manufacturers.

I'd say Ebay is getting swamped with gear from the ITT Tech auction. I'm eye balling some items but they have to go for low prices. IOW: If you can't sell your equipment now then you are probably better off storing it for a year or longer in order to wait for the prices go up again.

You can say that again. It's a flood. Good time to grab some stuff if they fit your needs.

I couldn't help myself.  I snagged one of the GW Instek GDM 8251A bench meters on eBay. From the ITT auction I suspect. Many more listed. I was able to get it for $95 + $20 shipping.  It will be nice to have a dual display bench meter for simultaneous voltage and current measurements. Photo from the listing. Mine should arrive next week.
