  • Page 4 2. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C520 and C540 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. After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
  • Page 5 - 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 of the amplifier are used.
