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.
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
colour bar signal(1Vp-p at 75 ohms terminated) and
controls to normal.
4. Voltages were taken with a high-impedance digital
voltmetre.
