[AMPS] Why class B??

Someone correct me if I am wrong, but if memory serves me, Class C should 
be about 75% efficient.  You can get efficiencies closer to 90% by doing 
a Class E design or one of the other funky topologies.  QST had an 
article a few months back on an HF class E amp.  Real small package but 
plenty of power.  But it's CW only.

If CW was my only mode of operation, I wouldn't even think of having a 
big class AB amp.  Doesn't make sense.
