Russian Cap ID

Hi,

can someone confirm the specs on this cap?
My photo translator comes up meaningless.

Cheers.

Made Oct 1961, so very likely now really due for replacement, even if it still actually has roughly the right capacitance, the case is very likely close to corroding through.

The quality of the russian parts varies a lot. Some are junk from the start and some are totally overkill  (more like military grade parts) in even more normal circuits.
So there is a chance the old capacitor could still outlast a new replacement.

Do not suggest just changing it. It's not a usual electrolytic cap but quite a special one. It's a glass sealed cap, so it should not lose any electrolyte over time and will probably outlast modern replacement. http://www.155la3.ru/egc.htm

There are 3 of them, one is shorted. 
One reads just over 2000uF, the other 1850uF or so, so I'm leaving those two alone for now.


This is a valve microphone power supply.
