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, don't short it out.
