What voltage range is that differential between those bases? If it doesn't alter the mains draw, then either something is funnny or the bias range is not enough to get both sides conducting. What is the mains draw then too?

It changes the voltage from 1.2V to 2.4V.

The amp draws about 330mA from the wall with no signal.

That sounds about right voltage wise, but that mains current seems low to me. I could be wrong.

What does current do through the various emitter resistors? Outputs, drivers, predrivers? Do the base voltages move on the later stages as well?
