Gambled and got a Keithley 614 broken from America. Turned out to be a broken power supply. I changed the 2lug triax to this 3lug triax: https://www.mouser.at/ProductDetail/Pomona-Electronics/5219?qs=%2fha2pyFaduhz5J4cFT4TO4O8VWthzn%252b3qNg4X6resj0=. I had to enlarge the mounting hole on the 614 to fit it in. For the new cable I made, I used RG316 coax and I put teflon tape under the heatshrink. I had gloves on all the time and cleaned the cable itself with isoprop. Tomorrow I will clean the board with some flux remover, because there is some flux left at the teflon solderpoints from the factory. Just for good measure. I also will calibrate it.
Also the unit was quite dirty. After veryfing that it worked, I took some time to really clean it up. Unfortunately some irreparable damage was done to the front panel.

PSU repair: LM317 and 7805 changed and batteries removed since the were completely discharged. Heatsink added to the 7805, becuase thermal stress might have been the cause of its failure. As recommended in the manual R147 was removed, since the 32V read below 29V. Around 28.5V. Removing that resistor brought it back up to 32V. Also the -32V is around that value. Before it was -29V. -5V lowered to -5.3V, but that should be fine.

Gamma spectrometer works. Now some yellow crystals need regenerating and testing.

I finally decided to take a picture of my $5 oscilloscope, the HP 54201D.  I was told that it wasn't working but it was money to my ham club.  Along with that, I got a Wavetek 186 5 MHz phase lock generator that was supposed to be working but isn't.  Trying to work with Erik at Wavetek to find a service manual for it.

I am displaying an approximately 13 MHz sine wave from my not warmed up HP 3312A FG.  The UI is.....................interesting.  I am starting to get the hang of it.  Quirky, like me.  My first thought was to see if I could sell it on and maybe make a bit of cash on it but the more I read the manual and play with it, the more I like it.  I think, for now, that I will keep it.  It also has the 3 10271A state data probes but no grabbers and only 1 connector with wires.  So far it has cleaned up well on the outside.  I do need to replace the velcro that holds the pouch closed.  I haven't peeked under her skirt yet.  If/when I do, I will post additional pics.

Certainly can't argue with that for 5 bucks.

Looks in nice condition tho you may want to have a look at the CRT cirucitry a bit. That image looks a bit weirdly bent. Maybe its just some trimmers that need a tweak or there is something magnetic near the CRT screwing it up, or it could be a component on its way out.

I can safely say there is nothing magnetic nearby.  Just more TE.  I have to get up the energy to open it up--wait, should probably do some reading in the service manual first.  I was on vacation last week and am happy to be back to work to get a vacation from my vacation. |O  I am playing with it in between doing things for work.

I owned one of those a decade ago, didn't keep it long though.
6 bit ADC's I could just about live with but the UI was just too much to handle.

Some renovations happening and old equipment found in cupboards, some was taken to be reused, some was slated for ewaste. I cant watch lightly used equipment go to waste so between a couple friends and myself, we rescue it. This doesnt happen all the time, but Ill keep intercepting it before its binned while it lasts.

PS: all it needed was a wipe down, really was lightly used.

This looks like a re-badged fluke 87 EX.  Maybe a 87(II)EX ... I could only find a picture of an 87V EX for comparison.  Looks like the 87(II) standard also had the yellow back light button and no marking for high resolution(4-1/2);  Maybe a different model as the there are some variation in the LCD layout.  If you don't look directly at the vendor/model you would mistake it for a fluke 87.

Well, that would explain it. But then I want to know under which influence the designers of the Createc Signalcomputer series aka Tek T201/T202 have been standing. Nothing I would endorse, so much is certain. And that is a feat.

I really don't know why I brought this or if it is even a score but well TEA and it has been 6 months since I brought ANY test gear of any sort :-DD

Advantest R6871E-DC 6.5 digit (displays up to 7 1/2) DC V A and Resistance only Multimeter. Does some fancy storage and integration and has at lower voltages a 10^10 ohm input impedance. Currently set to run on 100V and I haven't found anything online to know if that is changeable internally or not so I may need to break out the variac.

So a fun plaything while the 3458 budget grows to where it needs to be (Unless TiN keeps buying them all). $300 AUD so about $210 USD ETA late next week.

Nice, I saw that but decided against it.

The seller is a member of the forum too, different username to his eBay name though. Haven’t seen him around for a while, so might not be active anymore.

I brought a 6632b from him earlier in the year which was in excellent/mint condition. Chances are I will have a play with it test is against my gear and move it on when I get the $ for 8 1/2 digits.

If anyone else is interested this is the seller https://www.ebay.com.au/usr/silvia99gt?_trksid=p2057872.m2749.l2754

I'm sure the price of HP 3458 should drop once Keysight finally gets around to making a successor to it and people start switching to those instead. That is if TiN dosn't end up also buying all of those too that end up for sale...

Fingers crossed

Will be interesting to see if a 'significant' improvement can be made to call it a new model over say just a major overhaul and modernisation of the interface and such.

Hopefully TiN will be out of space before then  >:D

I'm honestly surprised they haven't at least made a B version replacing the UI etc. with that from their current devices.

I'm not sure if it qualifies as a "score" but I just purchased 2  HP 6268B 40V 30A power supplies.  Both in "used" condition.  One for $210 shipped and another for $334 shipped.

Will be using these primarily to do some large capacity battery charging and testing.

At 76 lbs (34.4 kg) each. They definitely could be used as boat anchors.

I was lucky again with TM500 gear: caught a DC503 timer/counter with Opt.1 (OCXO) for 40.-!
Listed as completely working (tested and aligned).
That is especially nice, as the defective one that did go before it yielded about the same!

Also, 5.5m of Keithley triaxial cable (without connectors) for 15.- and an older Neuberger catalogue for 1.-, which might help my research into the PKD4 modules and provide some info on the variants of the Unavo multimeter series.
And a pack of semiconductor spares, which are supposedly for HP gear. Even if they aren't, VN10KM FETs and Plessey matched pairs sound interesting and the remainder will be spares for whatever.
So, could be worse! 8)

Anchors or even ships ballast  :D There is times I wished my Manson 15V/60A had a few more volts as adding a 12V AGM to boost the voltage is a bit of a bodge.

I'm honestly surprised they haven't at least made a B version replacing the UI etc. with that from their current devices.

Thinking about it some more the A in traditional looks, mystique, heritage etc combined with see Humans our company got it 'perfect' X years ago and our bs bs spin newer designs, equipment are built to the same insert more spin  bs bs .....
