1. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C311, C313, C314, C506, C507, C508,
C584, C587, C588 and C708 through a 10 , 5 W resistortoground. DO NOTSHORT-CIRCUIT
DIRECTLY (witha screwdriverblade, forinstance), as this maydestroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
Current consumption at AC 230 V, 50 Hz inNO SIGNALmode shouldbe ~300 mA.

2. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions are noticed:
-Nosound isheard when the power isturned on.
-Stops during aperformance.
The function of this circuitryis toprevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are “shorted”, orif speakersystems withanimpedance less
thanthe indicatedratedimpedance of the amplifierare used.
If this occurs, followthe procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once againafter one minute.
Note:
Whenthe protection circuitryfunctions, the unit will not operate unless the poweris first turned
off and thenon again.
