I'm planning a 3x813 amp in grounded-grid. Primary use will be for
160-80-40-20 CW (Class C). What must I do if I occasionally wish to run the
amp in linear SSB service (Class B or AB)? Am I understanding correctly from
my reading that I need to add an adjustable grid bias voltage control for
adjusting cutoff, and an adjustable plate voltage control (variac?). It seems
like some amps use one way or the other but not both.
