Note:
• All capacitors are in µF unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
• All resistors are in ohms.
•
: nonflammable resistor.
•
: fusible resistor.
•
¢
: internal component.
•
: panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
•
: earth-ground.
•
: earth-chassis.
• All voltages are in V.
• Readings are taken with a 10 M digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production
tolerances.
•
*
: Can not be measured.
• NO MARK: Common
• <
> : SECAM
• (
) : NTSC 3.58 MHz
• Circled numbers are waveform references.
•
: B + bus.
•
: B – bus.
•
÷
: Signal path.

Divided circuit diagram
Schematic diagrams of A, D, and E boards are divided into serveral
pieces. Information to where the line is to be connected is printed
at the end of wach line.
For example, [ TO A1/5, A2/5_1 ] means the line is connected to
Ref. No. 1 of A(1/5) and A(2/5) schematic diagrams.
Ref. No.
