Re: Moog Prodigy: do capacitors model/type affect the sound?

2016-08-01 by marcmarc@...

Some types of caps, used in what is now vintage, start to leak there acid all over the board, Korg Ps3100/3200 is a good example. Copper traces eaten away with as a consequence power supply line fall out. A complete recap in this case is a must do.
Another reason to recap audio caps, is to lower the -3 dB Low Pass frequency point: using a higher value of the cap. This gives a deeper sound. This might not be original but sure is a gain.
