Daniel - that's about the age of mine as well. Can you confirm that yours
has ten jacks on the front, and not 12? (OPS2000 vs OPS2000B)
I'm happy to go in with you on a manual. I actually offered the Ebay seller
$10 + shipping this morning and they promptly rejected it and seemed miffed
(they responded that they reject all offers beneath half their asking
price). Maybe you should offer $20? (I suggest you as they seemed annoyed
with me)
What is wrong with yours? One of the 6.2V references is very much deceased
on mine, and the power light does not turn on. I don't know about anything
else as I'm too scared to probe around the insides of it without knowing
what's going on.
I wonder if the tube in these is unobtanium. I hope not.

OK, I'm officially looking for the same manual. My unit is also an
OPS-2000, probably from the mid 1970's. I think I dumpster dove it from
SUNY Stony Brook, which didn't really expand their physical sciences until
the 70's so it's not likely to be older than that, but from the looks of it
surely isn't younger.
There is a manual on ebay now:
I'm willing to split costs and do some scanning if someone here buys it.
Else, does anyone else have a copy they can share?
This is NOT off topic. I was thinking of posting to the Tek group
regarding using this power supply as a driver to test RM503 transformers
before installing them in my scope's mainframe. The output driver is a
series-pass power pentode (forgot which one) and the configuration is a bit
similar to what drives the R503 transformer in the scope. But the voltage
might be to high and the current too low from the OPS-2000. And then
finally, I checked the specs here:
(see p. 4).
It appears it only has a 200Hz bandwidth. That's a long way from the
20-50KHz I need to test the transformer. Still,I'd like to fix mine in case
it comes in useful for another repair.

I have a deceased Kepco OPS-2000 on my hands. I can't find a manual for
it anywhere. Kepco normally is a good source for manuals - but they want
$75 for a hard copy (no soft). Anybody got a PDF handy? All I need is the
schematics.
Thank you!
