1 Before Repair and Adjustment

TOP PREVIOUS NEXT

Disconnect AC power, discharge Power Supply Capacitors C301 through a 10 Ω, 5 W resistor to

ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver 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 220 V, 240 V, 60 Hz in NO SIGNAL mode should be ~100 mA

respectively.

2 Protection Circuitry

TOP PREVIOUS NEXT

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

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

●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 speaker systems with an impedance less than the indicated

rated impedance ofthe amplifier are used.

If 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 circuitry functions, the unit will not operate unless the power is first turned off and

then on again.
