IF YOUR AMPLIFIER WILL NOT TURN ON
Check the power to the unit. Check for tripped household circuit breakers, unplugged
extension cords or power-strip switches that may be turned off. Check the amps circuit
breaker located behind the 5U4 Rectifier tube. If the breaker is popped, re-set the breaker
and test your amp. If the circuit breaker continues to pop the amp need service. Also, check
your input and speaker output cables.
