Ooh, it's one of their Mil spec displays  8)  I was expecting a row of their 5082-7xxx single digit ones (like the polarity indicator).

For heavens sake, don't break that, I doubt you'd ever find another!


P.S. I notice they've mounted the polarity display upside down to get closer spacing - it's normally a +/- 1 display.

I brought a $19USD HP Counter that cost me $72.25USD to ship. You really don't need to worry.

I dare anyone to top paying 400% frt cost on TEA items :palm:

The Dots made me do it  ;D


That's a strange combination, perhaps the shittiest counter with the best display that HP had at the time. Usually only expensive, high end instruments had it, like HP 8340, 8350, 8662A/8663A and 8640B.

Bit strange to run a 6 digit display on a 50Meg counter too? I did also get it's better specced twin too from a different source because I have a plan  >:D

Photo below was as sent by it's former owner the day after both units were plugged together on my bench pile. The Oscillator adjustment SUX, when you go near it with a stick it flinches 20 counts making setting it good luck not correct tongue angle to set it accurately. A simple unclick to split the unit flick the internal/external reference switch and I have an accurate counter locked to the GPSDO. Insert the battery section from dotty when it arrives(with new LiPo's) and I have a portable UPS counter and GPSDO  8)

Well, it seems quite sure now that the little AC/DC-Electronics load will not stay with me. Why?
Because I scored a Transistor Devices DLP 50-60-1000. A bit on the massive side, but it will do until a compact H&H flies my way. That is, IF it is working or repairable. It was sold as 'untested' and was mine for 127.- all inclusive.

Maybe even better is a HP6825A 4-quadrant power supply, which is supposedly working and which did just cost me 75.- incl. postage. It is my first proper 4Q-unit and as such, it might start a series.

The DLP50-60-1000 is a cool unit.  I repaired one a while ago.  Mine need all the pots cleaned, the fan oiled, a couple of caps, and 1 power transistor. 

The entire base is a heavy aluminum heatsink with an amazing number of TO-3 power transistors.  I was impressed with how robust the design was.

Bought a few Tek 11801C's with matching SD-24 sampling heads. Being a sampling scope, they're only good for repetive stuff but then they are still the ducks guts. 20GHz BW *and* they double as TDR *and* you can plop in 4 modules for a total of 8 channels.



Old tech, obviously, but color display *and* touch screen. Fancy. And more responsive than more 'modern' machines.

I'm seriously considering keeping one, so the lab has a TDR handy. All the others: off to The Bay you go!

Now that is a score.

I been looking for one of these for a bit, the sampling modules are easy to come by but the scope mainframe is rare. What finally turned me away from it is seeing online that the mainframes are known to be very unreliable. To top it off fixing them is difficult due to cryptic error messages and hard to find parts.

Ended up instead with a bit newer HP sampling scope with a dual 20GHz sampling module.

Well, this one seems in good shape. If the others are equally good, I'll be one happy panda. Need to test the outputs etc but looks good thus far.

From what i hear the thing has a pretty extensive self test that takes a long time to run in order to test the stability of various parts. If it passes that and shows a waveform then its a good. If one of the sampling modules is busted then spare ones are easy to come by for a reasonable price.

Definitely a good idea to hold on to one of these.

I have heard of widescreen being a thing with scopes these days...but don't think that's the right way to do it.

But im sure a bit of poking around in the vertical deflection circuitry can sort it out. Nice price for it.

Pfftt.. Have you checked the 11801C? None of that widescreen rubbish. Ultra-narrow-screen FTW!

@ Martin.M

Decent price if you were sure there was only the display problem, no bad surprises on inputs or acquisition stuff.
All the same considering sample rate and memory depth, this is the kind of scope I'd buy only to fix and play around with a few hours before reselling.

That leaves you a little more play time  :-+
I followed the repair on the TEA thread, BD139 almost had it fixed before you bought it  :-DD

Yep, what bd139 doesn't know about scopes isn't worth knowing, he's the man.

I got a case with 6 prehistoric Teledyne Philbrick op-amps (you understand immediately where the 'brick' comes in) and the circuit elements formerly used with them. Complete with the leaflet (i'll scan it later).
It must have been part of some educational breadboard or related.

Factually, I would have gladly spent the 30€ for the heap of Pomona double plugs with solder turrets on the side. Or for the 3  clean and 3 cleanable Pomona 2-pole cables. And that case might come handy too.
So now I can add ready-made combinations on 3/4"-spaced 4mm plugs to my kits (in addition to the 50R from Beanflying). For example a PTC like Fluke sold with the 025, or RCs, or antiparallel diodes....

So I have splurged in the last week or so. Agilent 34461A, Fluke 335D neither of which were particular scores but are in great condition.

This is the score I had more or less given up on ever getting one of due to their normal second hand price. Sika Temperature Calibrator complete with different diameter wells. Delivered to my door will be circa $150USD  ;D

One very very broke but happy Bean.

An HPAK E3631A sold as parts only. Yes, it needed a rotary encoder...  not so bad. The display was pretty good, but I decided to replace it anyway, and keep the old one as a spare. Lots of floppy pins to deal with on that. All on the cheap. Wanted one of these for a long time, but was unwilling to pay even $300 for one.
