Vintage Synth Repair

Probably someting gone bad in the finally pre-amp
stage..bad op-amp, transistor, cap..take your
pick..Follow the circuit back from the Output jack is
what I would do. Dont know anything about Polivoks per
se but being Russian im guessing its a nightmare to
fix unless you're in Russia??

I say this because I repair vintage video games and we
once had an ultra rare russian video arcade machine in
called 'Polyplay' luckily it was fully working..but
the schematics were totally unavailable and every
component    in it was stamped with numbers and ID
codes that mean nothing in the west..

Whats the deal with these then in that way?
