360 means a complete phase?
So, in a single mosfet amp (like a szekeres like this)
It means that
-At Vin=0, Vg is at a value where the mosfet conducts
-At Vin=max, Vg is still at a value where the mosfet conducts
-At Vin=-max (negative peak), always the same...
Am I right?
What are the maximum peak values of a device's source line output?

An externally hosted image should be here but it was not working when we last tested it.

Yes, you are right. A device (transistor, tube...) which operates in class A is biased so that a current flow anytime across it. This is not the case in class B, because usually positive and negative inputs of the source signal are amplified separately, in symmetric configuration : each of the two devices conducts about half of time. Other classes are unusable for audio, or more complex.

Hi,
Simply stated:
"Class A amplifiers use one or more transistors that conduct during both the full positive and negative cycles of the signal."
However class A is not limited to SS amps. The early Tube ones were all class A.
