What is the IMD performance of this amplifier? Have you measured it? 
Have you seen measurements from a trustworthy lab?  I've seen 
observations on the internet that power must be limited to 100W to meet 
FCC IMD specs. There's enough splatter, clicks, and other trash on the 
ham bands without adding more.

I know from talking with Elecraft design engineers that the output of 
their rigs and power amplifiers is carefully limited so that their 
signals are always clean.
