I get from your answer that I should stick with the poly caps? Click to expand... Yes. decoupling caps on power pins?I should include but his is a duel power supply. Click to expand... The positive supply needs a capacitor to ground and the negative supply needs a separate capacitor to ground. decoupling between the V+ and V-? Click to expand... No. The two supply capacitors will be in series and provide good all around decoupling. Another question arose = the 10K duel pots are on another board using 2- 10 pin ribbon cables. the ground is on a 4 pin cable. should I use any decoupling caps? Click to expand... No. Pots do not oscillate if they do not have supply bypass capacitors. ICs do.
