What are you guys talking about?
Most of us use the amplifiers on SSB: that has a peak to average of
about 1 to 5. not only that, the peaks are reached about 5% of the time so
for the most time we are running peak tuned and underpowered 95% of the time
! Sooo the efficiency is in any case low (the average, which is the
important one!). the discussion has meaning only if we consider some
steadystate mode like CW or digital mode.
Please, don't start a flame over it: the discussion IS instructive
especially for the newer guys. Don't destroy it by getting personal!!!

Oh please, Joe. It was your answer to the original question that triggered
the
whole thread:
W4TV: "Running an amplifier in a mis-tuned condition (tune for 1500 W
Output
and drive to 800 W Out) is hazardous and inefficient. ".
I agreed about being inefficient but challenged you on the "hazardous".
Remember?
