screwheads, antenna, control shafts, handle brackets, etc. /
Equipment with antenna terminals should read between 2.7M
and3.9M to all exposed parts*. (
Fig.1
) / Equipment without
antenna terminals should read approximately infinity to all
exposed parts. (
Fig.2
) / *Note: Some exposed parts may be
isolated from the chassis by design. These will read infinity.
4. If the measurement is outside the specified limits, there is a
possibility of a shock hazard. The equipment should be repaired
and rechecked before it is returned to the customer.

2. Before Repair and adjustment
Disconnect AC power, discharge Power Supply Capacitors C566-569 and C591 through a 10 ,
5W resistor to ground. / DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for
instance), as this may destroy solid state devices. / Afterrepairs are completed, restore power
gradually using a variac, to avoid overcurrent. / Current consumption at AC120V, 60Hz in NO
SIGNAL mode should be less than 750mA.
3. Protection Circuitry
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 speaker systems with an impedance less
than the indicated rated impedance ofthe amplifier are used. / If this occurs, follow the procedure
