DESCRIPTION OF SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:
1. Voltages at test points are measured at the
supply voltage of AC 120V. Signals are fed by a color
bar signal generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.
WAVEFORM MEASUREMENT CONDI-TION:
1. Waveforms at test points are observed at the supply
voltage of AC 120V. Signals are fed by a color bar signal
generator for servicing purpose.
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. The unit of resistance "Ω" is omitted.
(K=kΩ=1000 Ω, M=MΩ).
2. All resistors are ± 5%, unless otherwise noted.
(J= ± 5%, F= ± 1%, D= ± 0.5%)
3. All resistors are 1/16W, unless otherwise noted.
4. All resistors are Carbon type, unless otherwise noted.

CAPACITOR
1. All capacitors are µF, unless otherwise noted.
(P=pF=µµF).
2. All capacitors are 50V, unless otherwise noted.
3. All capacitors are Ceramic type, unless otherwise noted.
(ML): Mylar
(PF): Polypro Film
CAUTION:
This circuit diagram is original one, therefore there may be a slight
difference from yours.
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET
BEFORE REPLACEING PARTS.
2. SEMICONDUCTOR HEAT SINKS SHOULD BE
REGARDED AS POTENTIAL SHOCK HAZARDS
WHEN THE CHASSIS IS OPERATING.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH " å " (
IMPORTANT FOR MAINTAINING THE SAFETY OF THE
SET. BE SURE TO REPLACE THESE PARTS WITH
SPECIFIED ONES FOR MAINTAINING THE SAFETY
AND PERFORMANCE OF THE SET.
