I Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C703, C704, C705 and C706 through a 109 , 5W resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.

After repairs are completed, restore power gradually using a variac, to avoid overcurrent.

Current consumption at AC 230 - 240 V, 50Hz in NO SIGNAL mode should be 240 ~ 330 mA.

I Protection Clrcuitry
The protection circuitry may have operated if either of the
following conditions are noticed :

' No sound is heard when the power is turned on.

- Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for
example, the positive and negative speaker connection wires
are "shorted", or if speakersystems with an impedance iessthan
the indicated rated impedance of the amplifier are used,

it this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.

Note:
When the protection circuitw functions, the unit will not operate
unless the power is first turned off and then on again.
