Ice-Tea's Score Thread
« on: December 18, 2019, 07:34:44 am »
As some of you know, what once started out as me trying to get some equipment for the lab, then grew into me making a buck on the side is still growing: I buy T&M gear. Lots of it. I've been spamming the TEA thread and Equipment Score thread with it but I figured that rather than poluting those threads any further I'd get my own. I've put it in the "Buy/Sell/Wanted" because, well, most of the stuff is for sale. That said, if mods (or even worse: Dave) is not happy with this, let me know.

Now, I won't post everything I get and put up for sale in detail, but I figured I'd highlight some of the quircky or unusual stuff for everyone's entertainment. Should at some point one of you be interested in any of it: it always pays to contact me outside eBay. It's always 10 or more % cheaper. In addition, the prices on eBay include VAT which means EU companies get another 21% discount. Customers outside the EU get the 21% discount as well, but that's often offset by higher shipping costs (and you may have to pay import duties).

That said: unit number one!

B&K Precision 2658

Handheld, battery powered 8.5Ghz SA. Weighs less than 2kg!

I'm ordering a new power brick and battery pack for it. Otherwise in pretty decent shape except for the discoloration in the middle of the screen. That's a real bummer. Also, not the "A" version, so no color sscreen for Ice-Tea.
Something you don't see very often (at least: I don't see it often..): switchable 50/75 ohm ranges!


For sale? YES! You may have to wait for the batttery pack to come in, though.

They don't get much bigger than this. If you think it's big, it's probably bigger in RL. With room for a pony.

But what is it? Well, the secret is in the plugin cards:

They allow a switchable matrix connection between DUT and measurement devices or signal sources or... Pretty much like this:

This unit has 3 dual 12x4 cards. Pretty niffy if you need to build a automated test setup. If you don't, you can still brag about the biggest tool in the shed and get all the ladies. But not really.

For sale? YES!

I'm a sucker for test gear, but I can't be arsed to try and scroll those pictures left and right to see what they are. Perhaps something viewable without a 4K display might attract the kind of olde pharte that would grab these?

dont forget the price, otherwise we just skip it and find in ebay

Yeah, problem is that prices change. If an item doesn't sell I'll drop the price after some time. Don't feel like having to update half the internet if I drop a price. Which is why I mentioned the eBay fee in the first post. Check the price on eBay, substract 10% for starters (and an additional 21% for companies). If it's close enough, PM me with a sob story to get more  :-DD

Eh? I didn't so much leave but it's a full time job to keep up with that thread. And I have two of those already  ^-^

Eh, sorry about that. Rescaled the first one, not the second one. I'll make sure to do better for the following units. The first one should be OK on a 1920*1080 monitor?

A quick solution would be the width command:

I actually have a 4K monitor but the browser is max 1200 wide. Things should scale to the window, not the hardware, although I accept you don't have that kind of choice when posting pix on a forum :)

Actually, I post most stuff on the German site. Stuff that makes sense to ship to the US should also show up on the .com site (sometimes with 'ask for shipping') but truth is I don't often enable it for 'Asia' in general. Too many unknowns. Best to browse through the german site, PM me if shipping to your country isn't listed.

Another one for ATE setups. A four channel Power Supply. Kinda. All channels supplying a whopping 10mA.  :-DD Seriously, though, mostly to be used for biasing purposes. Complemented by 8 digital IOs to enable/monitor the DUT.

Leaflet

I actually have several of those. Perhaps I should start thinking more like a salesman and less like an engineer and not post the pictures of the first one I verified but rather the best looking one :palm:

For sale? YES!

So you're running a little business and have been spamming the forums trying to shill the stuff you brought cheap to make a profit on. Now you want to spam the buy/sell/wanted forum. How original. :--

You misspelled "chill".

No the word is shill, if it was "chill" you would have been considerate to other sellers here and put links and prices all into one post that pointed to the Ebay sales.

Just exactly *how* would that be considerate to sellers? I wanted to have a nice thread where I could post interesting stuff once it came in, provide some background, share some impressions, maybe pop one open from time to time etc etc. I already explained why it's difficult to list prices here.

Not so quircky or special, just a 300W Chroma load.

Leaflet.

Pretty good units but two things to be aware of:

- This unit is very much a contender for the "Most Dick Place To Put A Range Switch"-Award.

Which is why I'm posting this: if this saves one of you from booting it up without checking I get a cookie.
- The transparant cover has a coating that is not very UV resistant and will peel. Had it in the past with other Croma units of this era, two out of three have it now. If you ever decide to buy one: beware.

For sale? YES!

Just wondering what you have over there... Looks like a stack of power supplies.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

EMI/Lambda TCR 600S1

I'll start with the easiest. Mostly because documentation is actually available for this one.

Leaflet



On the backside, some modifications from the previous owner:



Removing those reveals the full part number:



Which makes it a 600V, A, digital meter unit. Which is nice. Not so nice: 115V only.



From past experiences, I know some units have jumpers inside or the trafos can be wired differently to change the voltage range. No such luck in this case. I have the full manual, including schematics and, well, no. For some somewhat good news: it comes in at under 25kg, which means I can still ship it over the pond fairly easy.



Obligatory gut shot:



For sale? Not yet. Need to pick up a transformer before I can test this, even though I don't image there'd be much wrong with it.

EMI/Lambda TCR 300-6

300V, 6 amp for a total power of 1800W.

Leaflet

Model is a bit odd: 300-6-5-D-TC-0806. This does not exist:



There's a 300V/6A single phase model but in that case the model voltage decoding doesn't make sense (see previous post). A 300V 6A tri-phase unit is not supposed to exist, but there's a tri-phase connection for sure:



Voltage decode for 3-phase models doesn't match either. Not that I'm complaining. According to the silkscreen, you can use it with a single or 3-phase setup. The wide voltage range means you can hook it up in the US to 3-phase (or a single delta phase) 208V or over here to a single phase 230V. Word of caution: the safety covers are gone, which means there's exposed 230VAC and 300VDC over there. Buyer beware! Also, there's a broken off screw in terminal A, but connecting a single phase between B and C works just fine (there's actually a tape on the unit saying just that). Could remove the screw if anyone cares enough before a purchase.

EDIT:
Question: why does the TCR model number decoding not make sense?
Answer: because it's not a TCR, it's a EMS.  |O

Correct Leaflet
LCorrect Manual

Voltage decoding still doesn't make sense, though...

Other than that: works! Voltage measurement is a bit off, but should be fairly easy to adjust according to the manual. Same here: could do it before shipping out but I have other stuff to do right now.




Gut shot:



Two huge caps in there. No Gung Hong Lo here:



Everything in good shape. Perhaps some wear and tear around the primary cap:



EDIT: Holy Rotation Batman. Erhmm.. it's intentional. International studies have shown you should tilt your head at least every 30 minutes. You're welcome!

For sale? Sure

Brandenburg 475R Photomultiplier 2kV Power Supply

Don't go looking for datasheets, I tried and failed. If you have a copy somewhere, feel free to share.

Bit quircky for sure, this one. Old, and it looks like it too. It also works nicely. That is to say, the voltage is off by about 5% and the voltage meter is off by about 10% in the other direction.



I have two more of those, so maybe one of the others is closer. Love how it has one of those, what do you call it, dual scale decade rotaries? Love how it has a polarity switch too. Nice bit of kit. Not sure how much current it'll do, but guessing by the size of the heatsink (and I can't imagine it being anything else but linear) I'm guessing a few tens of mA?

Gut shot:



A few trim pots that can probably solve the 5% issue, but not touching that without knowing what it does. I'm guessing the MFD should be mFD (wouldn't *that* be something):



For sale: YES. If you're interested, I'll be happy to look through the 3 I have to see if any of the others are more accurate.

HI

The standard problem with these supplies is that the high voltage capacitors on the board with the rectifiers go Leakey, normally a change of them fixes all problems.

I have a manual somewhere but it would take some finding, from memory maximum current out is 20ma.

Hi George,

A manual would be great! The caps on the board at least 'seem' fine, no obvious spilling of gut going on ;)

Hi Kris

At present I cannot find the manual, moved workshop about three years ago it may have been lost in move.

These photomultiplier power supplies date from around 1970/5.

The capacitors I was referring to are the three yellow flat construction 0.1MFD 3KV working Suflex ones, they are a form of foil construction and go Leakey without any visible sign.

DELTA ELEKTRONIKA SM3540-D 0-35V,0-40A 1400W



I'll be honnest, there's a simple reason why this caught my eye: at my first job, all benches had one large and two smaller deltas on them. It made life easy: whenever something was off, you could be sure it wasn't the power supply. I'm well aware the same can be said for any decent quality bench PSU, but still. I was actually wondering how well their supplies are known outside The Netherlands and Belgium? They seem to be around since forever and don't seem to be going anywhere, which is an achievement in a world where you're squeezed between behemoths like HP/Whatever and cheap decent power supplies.

The datasheet has full schematics and explanation, as was the custom in those days.

All of that still makes only for a decent but unnoteworth entry. Except... For something I forgot and which makes it stand out. Wo can spot it? :

For sale? Yes!

Let me guess... It's probably about some acoustic properties. Did I win anything?

DELTA ELEKTRONIKA SM3540-D 0-35V,0-40A 1400W

These things are great. There's a few of the 3kW units at work, and one found it's way to my home lab from somewhere else. Here's the money shot:



Note the difference to Ice-Tea's 1.4kW unit (acoustic properties related), though this unit quite quit.
