SAFETY PRECAUTIONS IMPORTANT SAFETY NOTICE Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer. General Guidance Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet. An lsolation Transformer should always be used during the Do not use a line Isolation Transformer during this check. servicing of a receiver whose chassis is not isolated from the AC Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor power line. Use a transformer of adequate power rating as this between a known good earth ground (Water Pipe, Conduit, etc.) protects the technician from accidents resulting in personal injury and the exposed metallic parts. from electrical shocks. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. It will also protect the receiver and it's components from being Reverse plug the AC cord into the AC outlet and repeat AC voltage damaged by accidental shorts of the circuitary that may be measurements for each esposed metallic part.

When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB. Keep wires away from high voltage or high
