I wouldn't try it with My QRP K2.  Two suggestions:

(1) Get the KPA100 (delivers 100W+ on all bands without any problems)

(2) Get an AMP with higher gain so that 10-15w of drive will give you
whatever power you're seeking from the AMP.

Just an FYI: With my K2 in QRP configuration, I can get somewhere on the
lines of 400W out of an AL-811H with about 10-15w of drive.  Remember,
it's the first 500w that counts.
