[Elecraft] K3 TX power overshoot

[John Simmons]

I have a 6xxx K3 (not S). The output of the radio is monitored by an 
LP100A wattmeter set to peak reading. The K3 drives an AL80B. I have 
just done a TX power calibration. With the K3 power output set to 60 
watts and running SSB I will see about 64 watts output but occasionally 
see 74 watts peak on the LP100A. I am about to change to a solid state 
amp and am concerned that I will damage the solid state amp by overdriving.

Is this normal behavior? If not, anything I can check, change or align?
