The readings on AC coupling are useless.
These amps are better to troubleshoot with the outputs in the circuit and the rectifiers out of the circuit.

My fault The scope resets to ac each time i shut off power to it. Ill get that side again on dc. These at the via for the output transistors.
I will install new output transistors and remove the rectifiers.

Where is ground? Did you align the trace to the reference before probing the gate?
Can you do this?
Turn off all of the digital readout.
Set the scope to whatever manual mode is available.
Set the trace to the reference.
timebase to 5us
vertical amp to 5v/div
DC coupling
