Spotted an auction that had a "non-working" Tektronix 576 curve tracer as part of a lot of gear.  Threw in a bid of $125 thinking it couldn't be too hard to fix and won.  The curve tracer came with two adapters, the basic transistor and basic FET.  What was wrong?  Misadjustment of every knob on it, from focus and brightness on through positioning and a horrible combination of load resistor, step current and so on.  So after setting that right I have a nice curve tracer for way below market.

And then everything else, which included a repairable PCB router, 50A and 75A variable power supplies (both at 10 V), a Fluke 37 and 8840A multimeters, a Tektronix CDM250 multimeter, a slightly sick Tektronix 465B oscilloscope, several DAQs and several other odds and ends. 

Well worth the chance taken.

I didn't buy them, I saved them from the dumpster.
I'm lucky today :)
OMG where??

I’ve been struggling to even find used test gear (or other surplus) vendors in Switzerland... all the old gear seems to vanish into thin air!

Nice dumpster you have, may I ask where it is?  ;D ;D ;D
HP-3456A is my favorite DVM btw. Extremely well designed and easy to repair, without any unobtainable custom parts.

EPFL, Lausanne ;)

A nice save, indeed! Does the 34970 have the DMM option? Any modules in the slots?

I'm still looking for a HP 3437A going for little money because I've missed the time the HP 3437A were thrown out of the labs in numbers..  :palm:

Rémi and URI, what are you using (or going to use) the 3437A for? A companion to an analog scope? I got some stuff a while ago that included that model, but I'm curious what some modern use cases would be for it.

No, the slots of the 34970 are empty. I'm not sure about the 3437A, I will read the manual and see how I can integrate it to my setup.

That LCD certainly does not look very healthy.   :(

I hope that looks are deceiving in this case.

If it jams, force it.  If it breaks, you needed a new one anyway...

Looks like an extreme case LCD bleeding to me, hope I'm wrong but it looks like you need another screen on that pronto.

Unfortunately the LCD is completely dead. Powered the unit up and nothing.... Then when I pried the LCD out of its socket very carefully, it became even more cleare that it is broken.
Hoped to get a bargain on a "sold as is" unit.  :-// |O

It purely digits, no special symbols. It should be easy enough to make up a replacement with 7-segment LED digits and some simple circuitry.

I thought of that too, but there is not enough space for a standard 7-segment display.
I also contacted Fluke to see it they may have left some of these displays and how much one would cost.

If I were doing it I would clone the entire PCB and just change the display area to accomodate the new components. Then I'd transfer the other existing components to the new PCB.

My first LCR meter. Since there is a DC voltage bias adaptor with it, and I already have a HIOKI L2001 test tweezers and a Taobao Kelvin clip test leads, what I need to do next is to find a cheap chip test fixture for it.

My Aneng AN8008 arrived today via the slow boat from China.  I did some quick and dirty testing with some single digit resistors, which is more that I will need it for, and it worked a treat with a set of Brymen leads.  I am happy enough that I will pick up a spare in case I leave it onsite and some one covets it more than me.

Well, I bought it a long time ago... and managed to move it completely about a month ago... but now I've finished my 3+ weeks of mad overtime offsite for 2 different projects, I finally got my standing/sitting desk installed and running, and got my computer setup off my work bench.

Definitely the best desk I ever owned. thanks so much halcyon!

Finally got something Fluke that qualifies as a standard - a nice 731B. The batts were all original from 1977, exactly 40 years old.
They have been removed and a couple caps are installed in place until I make up some new battery packs.

Bought myself a Mitutoyo 500-196-20/30 which arrived today. Wow, it oozes quality, how did I put up with my old generic piece of crap for so long?

A three phase, 415V, 30kVA UPS, for $1.  Most of the batteries are removed, but it will be an interesting teardown when I get my hands on it.

This is a side effect of going down to Albury, for inspection of that huge machinery auction. Still not sure if I'll win a CNC lathe, but we'll see. I'm much less enthusiastic about that since discovering while talking with people there, that the machines on offer are less versatile than I'd thought. The factory bought machines only for specific manufacturing tasks, so they are very minimally optioned and tooled up. It was an interesting day though.

I took lots of photos, but not one of them comes anywhere near capturing the vastness of that place. I walked around in it all day, and still was alternately getting lost and finding things I'd not seen before.
The one inside view below is just a tiny corner, as marked on the building map.

Also, I think the past management were strange. There's a grid of isles throughout the factory, and on them the floor is painted with a glass-smooth paint. With oil everywhere, from the machines, and water (many roof leaks) it's literally the most slippery workspace walking surface I've ever encountered. Greased ball bearings on glass, in many places.

Also amazingly there is NO marking of any grid system. At first I thought I must be just not seeing it somehow, but no. Even the people that used to work there thought it was nuts. Not on the isle floor, or the columns, or the ceiling. Nothing.

During inspection the auction company handed out an A4-sized map of the building. Which made the details very tiny. They'd hand written their own grid refs along the diagram sides. But in several months of preparation for the auction and inspection, no one thought to write those numbers on the floor of the isles (near-white smooth paint) in felt pen or something. Result - the minute you walk a few modules away from an outer wall, then turn around a few times, you are lost again.

Which just made it more fun.

Turns out the place was shut down almost four years ago. All the machines have been sitting dead since then.
