Conduction angle affects peak plate current.

In this case, peak plate current is the plate current flowing at the peak of
the RF cycle, i.e. when the grid has made its most positive excursion. The
grid may still be negative with respect to the cathode at this time as, for
example, in AB1.
So I still maintain my argument that RL is fixed by the ratio of
instantaneous plate volts to instantaneous plate amps, and varaition of RL
with ZSAC is an implicit, and not an explicit, function.

But wouldn't this affect the 3/2 law? Beats me too - any more views out
there?
