[Elecraft] K3 sudden loss of RF power output

[Brett Howard]

I was the one that had a bad Q8/Q9 and R66 (actually the bad Q8/Q9 is
what creates the bad R66).  Anyway when I had this issue the RX was
pretty severly affected as well.  When I read your message I was
thinking it was the same problem that I'd had but the fact that your RX
seems ok makes me think it may be something else.  

My RX was working it just seemed really quite quiet from what was
expected.  Lemme know how your process goes... Being that I've had
something very similar happen I'm quite interested in how this goes for
you...
