5-3. PRINTED WIRING BOARDS ANDSCHEMATIC DIAGRAMS

Note:

•All capacitors are in µF unless otherwise noted. pF: µµF

Capacitors without voltage indication are all 50V.

•All resistors are in ohms.

kΩ = 1000Ω, MΩ = 1000kΩ

•Indication of resistance, which does not have one for rating electrical

power, is as follows.

Pitch: 5 mm

Rating electrical power: 1/4W(CHIP:1/10W)

•: 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-chassis.

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

•Readings are taken with a 10MΩ digital multimeter.

•Voltage variations may be noted due to normal production tolerances.

•All voltages are in V.

no mark : REC/PB

( ): REC

< > : PB

•Circled numbers are waveform reference.

•: B + line

•: B – line.

•÷: signal path.
