around it, I must be missing something.
What he's missing in his head is the fact that power out does double as
the plate voltage increases only by 1.414 while the plate resistance
stays the same. This used to flummox me, too... then one day as I stared
at the meters, it suddenly all clicked and now, it just happens
naturally when I tune my amps.

Those poor solid-state guys will never know the joy of seeing that Bird
reading suddenly double when the plate switch is flicked one more
position 8-D ...
