horns

["A. Foster" <monkeypuzzle1@xxxxxxx>]

Phillipe;
  This is anoying problem that happened to me on a few old radios, works
fine for a while, and then misbehaves, in a few cases it was a resistor
changing its value. Replace that resistor, preferably with a wire wound one
of the correct wattage and resistance, and you won't have the problem
anymore. It is obviously there for a reason, perhaps to limit current sraw,
don't short it out.
