It appears that my KPA500 has failed. It has a permanent "PA DISS" on all bands. Just before that fault it smelt like wire insulation was burning (no smoke). It has this condition on 160 - 6m. The fans seem to be running fine and the PA temp was 50C. I've run the KPA500 on JT65/MSK144/FT8 for over a month on 6m without a problem.
I was using the amp on 6m with 400w out (about all I can get on that band with 110vac). I had just finished a QSO on FT8. I can only get about 50w out before the "PA DISS" occurs. I've opened the top cover and see no obvious damage. Are there any other checks before sending it back to Elecraft?
