[sdiy] kinda offtopic...SH-101 repair?

[Mark Romberg]

lookin at a kinda damaged SH101, wondering if anyone knows how hard it 
would be to repair electronic problems with it?  the output is really 
low and it doesnt really seem to really develop a tone (VCO not 
oscillating? VCA not amplifying?).  i hav experience disassembling 
electronics and soldering things, im just wondering are there parts 
that are unobtainable or some other situation that would make it 
irreparable?

have nice days.
