the outputs from the LM837 feed into the 3916. This is not audio??

It is audio that you do not hear.

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?

No. Pots do not oscillate if they do not have supply bypass capacitors. ICs do.
