Specifications are subject to change without notice. Mass and dimensions are aproximate. 2. Total harmonic distortion is measured by the digital spectrum analyzer. 1 1. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C566~C569, C782 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. After repairs are completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC 240V, 50Hz in NO SIGNAL mode should be ~350mA respectively. 2. 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
