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