class-C PAs supposed to be around 66.%?). Also, as much power would be
dissipated in the PA stage as in the load.

I think this is easy to disprove in practice. I have an amp that is
probably class B, but it does not mater about the class. If I adjust it to
an input of 2000 watts from the DC power supply, I get out 1200 watts to a
resistive dummy load. If the above is true, I should have to input 2400
watts to the final stage. Now can someone tell me where the extra 400 watts
are comming from ? This 400 extra watts is not even counting on any loss in
the circuits.
