6-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

RM-871

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 MΩ digital multimeter.

• Readings are taken with a color-bar signal input.

• Voltage variations may be noted due to normal production

tolerances.

•

• NO MARK: Common

: Can not be measured.

*

• < > : SECAM

• ( ) : NTSC 3.58 MHz

• Circled numbers are waveform references.

•

: B + bus.

• :B – bus.

÷ : Signal path.
