SCHEMATIC DIAGRAM

WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY RADIATION PRECAUTION", "SAFETY

PRECAUTION" AND "PRODUCT SAFETY NOTICE" ON THE MANUAL FOR THIS MODEL.

CAUTION: The international hazard symbols "*" in the schematic diagram and the parts list designate components

which have special characteristics important for safety and should be replaced only with types identical to those in the

original circuit or specified in the parts list. The mounting position of replacements is to be identical with originals.

Before replacing any of these components, read carefully the PRODUCT SAFETY NOTICE on the MANUAL for this

model. Do not degrade the safety of the receiver through improper servicing.

NOTE:

1. RESISTOR

Resistance is shown in ohm [K = 1.000, M = 1.000.000]. All resistors are 1/6W and 5%

tolerance carbon resistor, unless otherwise noted as the following marks.

1/2R = Metal or Metal oxide of 1/2 watt

1/2S = Carbon compsistion of 1/2 watt

1RF = Fuse resistor of 1 watt

10W = Cement of 10 watt

K =

±10%

G =

±2%

F =

±1%

2. CAPACITOR

Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in

?F, and the values more than 1 in pF.

All capacitors are ceramic 50V, unless otherwise noted as the following marks.

Electolytic capacitor

Mylar capacitor

3. The parts indicated with " * " have special characteristics, and should be replaced with identical parts only.

4. Voltages read with DIGITAL MULTI-METER from point indicated to chassing ground, using a color bar signal with all

controls at normal, line voltage 120 volts.

5. Waveforms are taken receiving color bar signal with enough sensitivity.

6. Voltage reading shown are nominal values and may vary

±20% except H.V.
