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.
Whoah! Watch where that landed we might need it later.

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.



Armed with the service manual I dug into it.

Main board:

The cover actually has a battery and the battery charger as part of the included options (oven controlled oscillator was the other):

PWM DC-DC +5V main rail regulator section:

Probed around for obvious shorted capacitors or similar and found no issues. The fuse was the only thing that needed a replacement:

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:

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.


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.

Hi

Just scored this



A Solatron 7060 Multimeter for £60, a 6.5 digit multimeter
According to the plate on the back, this is a full blown G version  8)

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:

The third MSOX6004A from Keysight's competition, for $8.5k. Meanwhile, I sold my MSOX3104A for $5k, and I paid $100 to ship it, and $70 gas/$40 turnpike fee to pick my new MSOX6004A up. It sums up as $3.71k upgrading cost.

Very nice! Only 74.2 cents per upgraded MHz.

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.

This arrived today.

http://www.ebay.co.uk/itm/Tektronix-TAS485-Oscilloscope-/282131933198?_trksid=p2047675.l2557&ssPageName=STRK%3AMEBIDX%3AIT&nma=true&si=MEu7VsduO9y9F2CCsOb81S10eFE%253D&orig_cvip=true&rt=nc

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':



It is a Fluke 187 that looks like it has been run over by car.

Here is a picture of the backside:



And the inside of the top:



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:



I took the PCB assembly from the 'roadkill' unit and put it in the electrically damaged unit and I have a working Fluke 187:



I have checked all the ranges with my Fluke 5101 calibrator and everything seems to be working properly.

Regards,

Jay_Diddy_B

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:


The cover didn't look too bad.

But, under the cover:



More dirt:



Giant 'dust bunnies':



This was the cause of the problem, a damaged 10turn potentiometer:



After cleaning:



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.

Regards,

Jay_Diddy_B

Nice job on both.  :-/O  :-+  Not only did you save some good equipment, you got to keep one.  :-DMM

Definitely a good deal, and FWIW, I'd say the road kill unit was your payment for fixing the HP (sounds positive, as this story is IMHO).

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.

Is that a 2012 model ?
Does Agilent offer 6Y warranty , or where do you check for a valid warranty ?

The scope has a 5 year warranty - you can check for warranty status here using the model/serial #:

5 Years on this one. It's a 2013 unit. Add 52 to 61. I forget what the significance of 1961 is, I'm sure someone remembers.
