Sorry,
Eimac said different in "care and feeding of power grid
tubes".
Ahhha... in that example, Eimac is calling the SWING of
plate or grid voltage "peak".
*I've* always considered the "peak plate voltage" to be the most
positive voltage that the plate can attain (and the
corollary is the "negative peak plate voltage" would be the
most negative plate voltage), and I think the rest
of us have done so, too. But in that example, that writer is NOT
using that same "definition" and in fact, at the end of that first
paragraph, he seems to mix (or at least combine) terms when he
says "This is a peak swing of 220 volts, and the peak
r-f grid voltage is 220 volts.".?
And just prior to that, he writes "... the greatest each value swings
away from the d-c value. This is known as the peak value
of the r-f voltage."
Looks like a matter of semantics? 8-)
