W or less unless otherwise

specified.

•

%

: indicates tolerance.

•

f

: internal component.

•

C

: panel designation.

•

A

: B+ Line.

• Power voltage is dc 14.4V and fed with regulated dc power

supply from ACC and BATT cords.

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

Voltage variations may be noted due to normal produc-
tion tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc-
tion tolerances.

• Circled numbers refer to waveforms.

• Signal path.

J

: CD

• X

: parts extracted from the component side.

• Y

: parts extracted from the conductor side.

•

a

: Through hole.

•

: Pattern from the side which enables seeing.

(The other layer’s patterns are not indicated.)

Note: The components identified by mark
