Vintage Synth Repair

In power supplies, I'd recommend Nichicon HE/UHE caps, their MTBF is
much longer than most capacitors. In the signal path, people recommend
poly#### film capacitors to replace electrolytics, since they're
non-polarized and have always good characteristics for audio. You
simply eliminate the need to look through tons of different types of
capactiors, there are no bad sounding film caps. There are two common
types, polypropylene and polyester. Polypropylenes are said to sound
better, but they start failing after 20-25 years. Polyesters don't
have this problem.
