Thanks Ron, the links were quite helpful. I did learn a lot but a lot of it was over my head. Particularly with respect to the oscillator in the FM detector can. Should this run at 9.1 Mhz? Should it be adjustable via the trimmer in the circuit? Again, mine is running at 10.4 and the trimmer does nothing. I do receive FM stations but the sound quality could be better. Is it safe to say the FM 1000 tube is OK (I have no tester) if I am receiving FM? I do have excessive hum on the FM band only. Everything has been recaped.
