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.

•f: nonflammable resistor.

•F: fusible resistor.

•¢: internal component.

•p: panel designation, and adjustment for repair.

• All variable and adjustable resistors have characteristic curve B,

unless otherwise noted.

•e: earth-ground.

•E: 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.

• Circled numbers are waveform references.

•s: B + bus.

•S: B – bus.
