The grid chokes in my TL-922 were replaced with 10 ohm resistors
by the previous owner. The amp works fine except on 10 M where the
resistors go up in smoke within a few seconds.
This bring up several questions.
1. Is the amplifier oscillating on 10 M?
2. Should I replace the resistors with the factory 470 uH chokes
or directly ground the grids?
3. Where can I get replacement grid chokes?
4. I?ve read about adding/increasing negative feedback. Does anyone
have suggestions?
Thanks for any and all comments.
