Nice catch, KT. Hopefully, the corrosion isn't too bad. :-DMM

Thanks, bitseeker.  The corrosion is on a couple of places, fortunately not everywhere.  Perhaps some moisture got into the unit over time.  Otherwise it is in good physical condition, so I just couldn’t pass it up.  :popcorn:

2 pieces hp 3478a  $29usd each, free shiping, one with u.c. rom fail but even with the reported error it works perfectly and still on calibration :)

best regards

And I thought I scored by getting one of my 2 for $45 US.   |O |O |O  Well done.

HP 5345A Electronic Counter, $59.99 + $29.59 shipping

793800-0

This thing is heavy, but at least is full of other things :D Was listed as power on no further testing, and it works pretty well. It gets around 7 digits right, I'm waiting for a PLL-GPSDO to use as external reference and will see if it gets better.

With that reference in it should be pretty good, far better than 7 digits, as long as the 10544A is working properly.

In fact after half an hour of warming it is much better, this is from my $99 eBay PLL-GPSDO

I know a lot of you guys have the big higher end stuff, but I'm just a home hobbyist. 

I just picked up a GW Instek GPD-3303S for $199. (+$20 shipping) I was considering a brand new one at well over twice the price.  I'm pretty excited to have gotten it.

Why exactly do people feel I should have read their post before I responded?  As if that was necessary for me to get my point across.

Just picked up a Fluke Cal 5725a and a HP 54522a. Both like new. Kind of dont know what to do with it. ANyone know any good place to sell it. 

Dont really think this is technically test equipment, but also picked up a Yxlon WL 3002 Xray chiller.

I got a few weeks ago a Tektronix digitizer TWD120 for the price of shipping. Really nice kit, but hard to setup (uses SCSI2 interface, Win3.11 application) and noisy, but it is quite a journey to my past of SCSI expert among a sea of IDEs...

Photos and a few comments are shown at the post below.

At the moment I am trying to make it work on a laptop Dell Inspiron 2200 with a PCMCIA SCSI card APA1450 - no joy so far. I may need a BusToaster or a APA1480.

By coincidence I also bought one of the GPD-3303S supplies on eBay from that same seller in Maryland and it arrived today. They are a nice supply and in good condition.

If you check the forums you will see that there are 2 versions of this supply where the newer one was redesigned so both the GPD-3303S three output and the GPD4303S four output could use a lot of common parts, including the same main circuit board. From what I read it appears that there was a bug that crept in with the new design that caused some problems. Both you and I got the older version that works like it should. My supply seems to be pretty darn close but I think I'll go through the long calibration procedure in the service manual and check everything out.

Nice, mine arrived pretty tightly dialed in too.  I believe it said they were refurbishing them.   So far I'm very happy with it.

Correct. The newer model, which doesn't have any gaps between channels, has an overshoot issue. I don't recall any more which channel it was. The older models is fine. I do recall there was a thread with some potential fixes to the overshooting, in case anyone has the problematic variation.

I think I spot a Marconi 2370 spectrum analyser. Seriously weird bit of kit with a very early storage technology. Didn't realise they'd got across the Atlantic. And maybe a Gould storage scope above the Keithley ?

Good grab. The Gossen Mavo30 will leave me again into a lady engineer's hands, as I shot myself a TekMeter THM560 for 100.-
That was a good deal.
I bought the THM565 a while back a little more.
Do you have the computer adaptor for yours?

Apparently they did ;) Unfortunately without the connecting cable. |O

My 3457a arrived and looks OK.
The mains filter had already spued its guts, not too much mess compared to some I've seen and now replaced.
Battery voltage OK.
Quick test using my basic hand DMM and the 3457 appears to work on DCV DCI and resistance. AC ranges to check.
So far so good :-)
