Typical efficiency of a push pull amp in class AB is 65 to 70%
For class D it is 80-85%, for a class E amp 90-95%.
In theory class E has no losses ... if you could find the perfect switch (no turn-on / turn-off time, no resistance) and coils.

A BIT LESS!!!!! at least 50% less than a class D or E, which should yield 90% with a proper design.

OK Brian, thanks for the info. Yes, I realise the efficiency will be a bit less. Seems different people have had quite different experiences using AF techniques/ready made amps etc.
Thanks, 73,
Chris, G4AYT.
