DIAGRAMS

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
• % : indicates tolerance.
• C : panel designation.
The components identified by mark 0 or
dotted line with mark 0 are critical for safety.
Replace only with part number specified.
• 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 jack (J201).
• Voltages and waveforms are dc with respect to ground in playback
mode.
no mark : CD PLAY
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler-
ances.
• Circled numbers refer to waveforms.
• Signal path.
