I think you posted the voltages at the pins of the dual opamp.
Its Pin 1 has a very high AC output voltage and the 2nd opamp and transistors should rectify it and amplify it but they don't.
Check C4 (330nF which is 0.33uF), R9 (56k) and R8 100k). Check that the emitter of one of the transistors isn't shorted to ground.

Checked all that you mentioned. Nothing.

I will lay low for a while till I can get some stuff sorted out and I get the stuff I need from DigiKey. Until then, I am humbly greatful for the insight and time audioguru. You are the man :)
