F 50WV or less are not

indicated except for electrolytics and tantalums.

• All electrolytics are in 50V unless otherwise specified.

• All resistors are in ohms.

 : 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 10M

Ω

 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.
