Can anyone tell me what the connections going from Grid 2 on the 6v6's in the attached schem are going to on the opt? My opt only has three wires to connecdt to on that side.Also what does the resistor and cap in parallel accomplish up at the top of the schem?

Since ya aint got no UL taps on yr output xfmr; youa gonna hafta run the 6v6s in either triode or tetrode. Iffa you can, up the bias (6v6s) to class A in tetrode; It will sound unlike anything you have heard before.
Push pull triode sounds interesting; might hae to give that a try.
Good or bad diffent? : )Know of any schems for making it tetrode?

The 1K is also the cathode bias resistor for the first stage.
