[Elecraft] K-2 /100 Power Output Drop

[Alexey Kats]

It sounds like half of your PA shuts down somewhere close to the final
stage transistors. Could it be a bad soldered connection somewhere
which loses connection after brief warm-up? Or a partially stripped
wire in one of symmetric transformers? I'd start with checking all the
connections around PA transistors in final stage. (I had similar
experience with a powerful AF amplifier long time ago, but there was
another hint - audio was badly distorted.)
