Looks like you have well and truly joined Volt Nuttery and found the elusive BWD PS as well
Yup, could not help myself! Its not like I need or was looking for the Fluke 731B or 510A either nor another Keithley 197, but they were so cute. I walked into an Alladin's cave of old electronic test equipment and I lost control. Walked away with more than I planned to.
Even called a work mate, to see if he wanted anything, and for whom I picked up a HP 3582A and another Keithley 197.
The HP 419 null meter is a good thing if it is working condition too. Just watch out for the Mercury cell in it and most likely some very crusty NiCads in the back.

Yup tomorrows job, open and check the fluke and HP meters before power up. Also check the caps in the 7603 before power up.
The Fluke 732B and 510A batteries look ok and seem to work OK initially, though need to log over time to see if stable. Keithley 197 is good too. Looking good so far!
I just scored a HP 3708A for 1000 Yen (about 10 bucks, give or take). At that price I couldn't say no, no matter how full my room is with gear (I bought a 25U rack last week to stack stuff in and I already need another...
)
Now I just gotta figure out what to do with it.
It also apparently has option 030, but that isn't listed in the manual, so I wonder what it is.....
Photo from the auction I just won now.
Wow, that's quite a score. Nice one, TO!

April has just begone and with it the second quartal, but the Jammy Git Award for both will be hard to take from you.
I do enjoy me a bit of a deal on Yahoo Auctions.
That along with the junk stores in Akihabara here in Tokyo have my wallet looking sad (but not too sad on occasions such as this.
)
An impulse buy:
It is a GW Instek LCR-821 high precission LCR meter. Basic accuracy of 0.05%, measurement frequency up to 200kHz and it can measure very low values as well (resistance from 10 micro-Ohm which is nice when I need to deal with Li-ion cells). I was kind of eye balling a higher end LCR meter for a while without really wanting to buy one. However this thread
https://www.eevblog.com/forum/testgear/gw-instek-lcr819-and-the-mystery-of-password/ triggered doing a search on Ebay. Just for kicks I low balled the LCR-821 and the seller accepted. The unit arrived today and after desinfection / decontamination I tested it. At first it didn't seem to work but it turned out the 'range hold' mode was enabled.
I want to clean it up (take the front panel apart to give the plastic and the rubber buttons a good cleaning) and maybe it makes for a nice TFT conversion project as well. The insides look pretty simple. A 68000 CPU seems to drive a whole bunch of Lattice CPLDs. The power supply is a standard Meanwell PSU.
Ive been told I need help, possibly true, been trying to forget I saw this a few weeks ago, but I caved....

That HP 220A is cute - I don't recall ever seeing one, or even noticing it in the catalogs. Interesting. Nice haul!

It was to cute to leave, never seen one before either, didnt need one but couldnt help myself....
PS: its a fairly simple device inside, not much to it.

I did sit there contemplating my TEA, as the 734a warmed up, but by the time I finished my cup of tea I figured it was all good...
oops, one 732B blew the IEC line filter module (Schaffner FN376-2/22) during warmup (after about 3hrs). Time to buy 4 replacements (along with the four new batteries).
PS: Inlet module on the 732b (line filter/transformer) is enclosed in a small metal cube riveted together and not screwed. Date markings indicate 1992 manufacture.
At least the inlet module case helped contain the filter guts maybe?
Given how awful they are when they let go, one wonders how Schaffner parts still get designed into anything by engineers who have experienced it.

You probably answered your own question there.

I was with him. We tried to help each other. Didn't really work. Only thing that helped was that the 4wd was full of haul and we could not fit any more in for the trip home.

RIFA inside. Looks pretty clean, they often spill some brown tar all over the place. Consider yourself lucky
