: 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 (J401).
• 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 M
Ω
).
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.

Note:
The components identi-
fied by mark

are criti-
cal for safety.
Replace only with part
number specified.
