4-3. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

Note:

•All capacitors are in μF unless otherwise noted. pF : μμF 50WV or less are not indicated except for electrolytics and tantalums.

•All electrolytics are in 50V unless otherwise specified.

•All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ

•Indication of resistance, which dose not have one for rating electrical power, is as follows.

Pitch : 5mm

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

• : internal component.

• : panel designation and adjustment for repair.

•All variable and adjustable resistors have characteristic curve B, unless other- wise noted.

•As to the voltage volue shown by the semiconductors on the Shematic Dia- gram, see the another list

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

•Readings are taken with a 10MΩ digital multimeter.

•Voltages are dc with respect to ground unless otherwise noted.

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

•All voltages are in V.

*: Measurement impossibillity.

•v : B+line.

• : signal path.

•Circled numbers are waveform references.
