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.

=1000

, M

=1000k

•

Indication of resistance, which dose not have one for rating electrical power

, is

as follows.

Pitch : 5mm

Rating electrical power :

W (CHIP

•

: 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

digital multimeter

•

oltages are dc with respect to ground unless otherwise noted.

•

oltage variations may be noted due to normal production tolerances.

•

All voltages are in V

: Measurement impossibillity

•

: B+line.

•

: signal path.

•

Circled numbers are waveform references.
