3-1. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

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.

•Voltage value is non signal state.

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

•s : B + bus.

•S : B – bus.
