[Elecraft] K3 tune button

[Don Wilhelm]

Steve,

You are correct that the FINAL tuning of an amplifier with adjustable L 
and C controls should be done at full power, but I see no need for those 
"pulsers" - do a preliminary adjustment with a low TUNE power, and then 
do a quick "touch-up" at the full power level - that only takes a couple 
seconds for the final tuning.
We hams have been tuning amplifiers at full power for ages and ages, 
long before "pulsers" became available, and that is how we did it - get 
close with low drive to the amp and touch it up at full power it works 
every time, and no harm to the tubes (unless you dally at the full power 
touch-up).

73,
