Default Re: Toaster FB10 elusive fault

Scope the output of the detector, if this drops with the volume you can discount the audio stages.
You need to try to isolate the stage in which the gain is reducing, no use guessing. The AGC changing could be a clue but it doesn't show which stage is faulty.

Have you checked voltages on the radio with and without the fault?
