I was also of the firm opinion not to use ALC, but as my K3's power  
output fluctuates a lot in SSB and sometimes for no reason also trips  
the amps in CW I have ordered the ALC mod to make sure I protect the  
amp.

When I set power for 50 watts output and confirm this power level with  
"TUNE", I easily get 65+ watts on SSB within a few seconds after  
keying up and start talking. Then slowly the power settles down to the  
set level or even below. I will do the mod and hook up ALC as a safe  
guard and keep it that way until Elecraft finds a solution to my (and  
others) fluctuating power problem.
