Parts description and reading in schematic diagram
1. The parts specification of resistors, capacitors and
coils are expressed in designated code. Please check
the parts description by the following code table.
. 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.
