Subject: Re: [PolySix] Refurb VS Replace P6 Power Supply - strange high pitch issue

You'll see decoupling caps (the values can vary) right around the ICs.  If you have a noisy power supply, you're arsed to begin with.  An incredible range of problems can be solved by fixing a power supply (in all equipment, not just the P6 specifically).

tty good length the importance of various capacitor purposes within synthesizers, particularly decoupling capacitors. For those he mentions that many synths have a plethora of .1uF caps all around circuits, and that they serve to keep a lot of noise out, such as high frequency noise.
In the polysix circuits, there are lots of .01uF, not .1uF. I'm not familiar yet enough with circuit theory to say wether or not those are the decoupling caps for the polysix. Can someone tell me?
