Introduction
A 20 (?) year old Yamaha rxe100 amplifier with built -in tuner had an intermittent problem with both speakers turning off erratically. This gradually got worse with age, til it was only useable on the headphones. When the speakers turned on or off I could hear a click, which was the speaker relay closing or opening. (Not to be confused with quieter sound of the power relay which turns on almost instantaneously when the standby/on button is pressed)
The fault was believed to be due to failure of the speaker protection circuitry. The work-around was to solder a wire across the speaker relay pins having checked that the dc offset in the amplifier was satisfactory.
