I notice from the schematic, that there is also a tertiary winding which is fed to the the driver stage. Seems a long shot, but could it be out of phase?
Also, what are you using to measure the capacitor. A digital capacitance meter will mask a poor power factor. In other words, the cap could still be open. Can you substitute another?

Yes, and I've tried it with the feedback ladder disconnected - no difference. >How about running solid tone for maybe five minutes. >And then look for something that's overly warm. Good thought - thanks.
