During KPA500 beta, I was loaned one for a major RTTY contest weekend
and told to run it "with all the lights lit." I did, and it worked fine.
In the 3-4 years I've owned one, I regularly run it at full power in
digital modes on all bands, 160-6M. When it gets warm, the fan speeds
up, but it continues to put out full power. This includes digital modes
like FSK441 and JT65A on 6M, and lots of RTTY on the HF bands.
I cannot get my KPA500 to run more than about 200W on 6M without getting
a PA DISS fault. Temp is not even up to 60C yet.
Between that and the KAT500 coming 'untuned' and faulting in the middle
of a QSO on 10M, I'm about ready to throw them both in the
trash and go back to my tube amp.
