Don, you pinpointed the problem exactly! In the buffer stage, I'm afraid I installed the wrong device for Q14 (really careless, to say the least). I pulled out the ZVN4424A, and replaced it with a new 2N4124, and I now have power output on 20m.
However, I do still have a problem on 20m. I did not have a clean sound on the sidetone (sounded like heavy key clicks) on 40m before replacing Q14 today. After replacing Q14 I now have a nasty sort of two-tone, worse towards 5 watts out. Sounds like an overload, or maybe RF getting in somewhere. I have the STL set way down to 1 or 2, and that controls the volume, but the sidetone is still pretty awful. In addition, I'm getting a loud sidetone when I activate the TUNE function on 20m (not true on 40m). Any ideas on this new problem? Many, many thanks for your help.
