■ Parts description and reading in schematic diagram

1. The parts specification of resistors, capacitors and . The parts spec icatio
coils are expressed in designated code. Please check coils s are e s press d i
the parts description by the following code table. the p parts d
2. Some of transistors and diodes are indicated in mark
for the substitution of parts name. Please check the
parts name by the following code table.
3. Voltages and waveforms were taken with a video color
bar signal(1Vp-p at 75 ohms terminated) and controls
to normal.
4. Voltages were taken with a high-impedance digital
voltmeter.
