Your circuit diagram might not give the bias voltage but this one does

It's yonks since I've been anywhere near a valve design, I'd forgotten
just how basic a lot of it is. That amp is not much different to the
stuff in my 1964 ARRL handbook under 'modulators'......
AFAIK the 6dq6a's were designated for modulation duty
As you say the business end of any power amp is close to that of a
modulator.
