Charlie: I have an old Alpha 78 on the bench. It retains the original
tubes and has seen many a contest over the years. Puts out 90%+ of what
it would do with new tubes, and I have never ever tuned it using a peak
reading wattmeter. I usually keep a Drake W4 in line and I tune for
maximum output when I need to tune it....which is rare. I keep a cheat
sheet on the amps with the tune and load cap settings on it, one set for
cw and one for ssb. In the heat of battle it is a 5 second band change
and maybe maybe a 2 second tweak if the wattmeter says I need to.
(assuming I am not using the passband settings). 73 bob de w9ge
