NOTE ON SAFTY : Symbol ※Fire or electrical shock hazard. Only original parts should be used to replaced any part marked with symbol ※.

Any other component substitution (other than original type), may increase risk of fire or electrical shock hazard.

Service Note

Cautions during Inspection and Repair

1. Keep in mind the safety warnings

The safety instructions are shown as the labels or printings on the exterior, the

inside chassis or the parts, etc. Refer to the instructions when proceeding with

inspection or repair.

2. Use only the specified parts for replacement

The selected parts are used at critical area to reduce fire hazard or electrical

shock. So when replacing these parts where designaged with marks or

※marks on the schematic diagram or the parts list, ensure to use only the

same parts.

3. Ensure to dress back the AC (Mains) cord to the original position

If for some reason, the AC cord is moved or partially disassembled, ensure to re-

route or assemble back to the original position. The AC cord area is protected and

secured by tubing and insulation materials for the sake of safety, so that no loose

wire will touch and cause fire hazard and electrical shock.

4. Check for safety aspects after inspection or repair

Ensure all parts, such as screws or wires, removed during inspection or repair are

secured back to the original positions, and check visually for any anomaly. Also

check for any electrical leakage or resistance to maintain the safety.

Adjustment

Instruments : DC milli–voltmeter

Notes : Prior to Bias Adjustment, run about 5minutes with rated output(8ohms)

and warm up Power Transistor and Heat Sink. Set input off.
