Vintage Synth Repair

Thanks for the info and advice. I'll go ahead wit the caps on the PSU and work my way down. It's just something I've always heard. These older caps bring something to the signal but it sounds like that's not quite right, is it?

So the caps in the signal path won't really affect sound here? Really? I would think they would ins some way. I could see that in the PSU but everywhere?
