Tube class-C amps often self-bias (via grid rectification) when
operating normally. Without drive, they often have high, sometimes

Toobz? I was talking of transistors. Many tranny designs for Class C
RF utilize self-bias, too, but there is still no quiescent current!


What makes an amp Class C is a low conduction angle while operating.
When it's not operating, is has no class at all.

Burridge? shudder


He said surgeon, not sturgeon.
