Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted.  pF: µµF

50 WV or less are not indicated except for electrolytics
and tantalums.

• All resistors are in 

Ω

 and

W or less unless otherwise

specified.

•

f

: internal component.

•

C

: panel designation.

Note on Printed Wiring Board:
•

X

: parts extracted from the component side.

•

Y

: parts extracted from the conductor side.

•

: Pattern from the side which enables seeing.

(The other layers' patterns are not indicated.)

• Indication of transistor

•

A

: B+ Line.

•

B

: B– Line.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.
no mark : CD PLAY

• 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 PLAY

c

: DIGITAL OUT
