doubt it's a function of the amp but the rig driving the amp....

Set output at 30 watts to drive amp
sometimes output appears to sneak up to the setting 
more so on initial send , like rig is testing the waters 

JEFF - if you'll do digital LOTW (FT8, RTTY, FT4, etc.), I'll call you with
my call 3x !!

You are so correct Victor. I have a special problem with my call (W8HW) on
CW as often would get logged as "W8SW" if I only sent it once. I quickly
learned to send my call sign two (2) times in pile-ups and that serves to
reduce errors and reduces "busted logs" problems. It takes less time to send
call twice and get it right than it does to correct it later, and
later_often_ does _NOT_ work as by then the pile up starts again and makes
it impossible to correct.
