I think a two-tone test is the best evaluation tool.. The generator is built
into the K3 if you have another receiver that you can use to listen to the amp
output. I use an SDR-IQ which is a very nice tool for this but any other SDR
would do.
Sorry for your pain.

I was operating in the ARRL-CW contest this morning and on 20m, with a 1.2:1
SWR on the Yagi, all of a sudden I saw my power drop to about 450-500W with
about 40W in. Worked a few stations but not as easily as when I turned
everything on this morning. Switched over to phone and made a few contacts.
Audio is fine barefoot with 100W out of the K3s-which suffered blown finals
itself during CQWW SSB last fall, but with the amp in I got reports that my
audio was badly distorted.
Before I send it in, is there anything I should look at or any diagnostics I
can easily perform? For the cost of this, I'd have thought protection would
have kicked in to prevent anything untoward from happening. I'm in complete
disbelief, to be honest.
