Hi! New here in the forum. Please bare with me,
So I have Priboj 50 Amp. And it works fine but I want to change the capacitors.. But it’s all in Russian.. can’t really get the info on these capacitors. One capacitor reads “ K50-12 300B 200mk” I guess 300b is for the voltage. And MK is for the farad.
So I’m looking for a Russian speaking or somebody who’s got knowledge on this amplifier
Thanks!

Welcome to the forum.
I'm guessing you are not going to get too much information on this amp without actually finding a circuit diagram.
If it works fine why mess with it?

The capacitors is of poor quality. And has been sitting there since the Soviet union
