[Elecraft] K3: 630m amplifiers

[Phil Wheeler]

I'd have to dig out my old circuit diagrams, but 
it seems like when we used Class C amps "back in 
the day" (1950's and 60s) we keyed the output 
stage, not only the driver as with linear amps -- 
and we modulated the output stage in the AM days, too.
