Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
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

specified.
•%: indicates tolerance.
• C : panel designation.
• A : B+ Line.
•Total current is measured with CD installed.
•Power voltage is dc 4.5 V and fed with regulated dc power
supply from DC IN 4.5V jack (J401).
•Voltages and waveforms are dc with respect to ground in
CD play mode.
no mark : CD PLAY
•Voltages are taken with a VOM (Input impedance 10 MΩ).
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.
