Note:
The components identified by
mark 0 or dotted line with mark
0 are critical for safety.
Replace only with part number
specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro spécifié.

DIAGRAMS
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.)
• MAIN board is multi-layer printed board. However, the pat-
terns of intermediate-layer have not been included in the dia-
gram.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
• WAVEFORMS
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
1
/
4
W or less unless otherwise 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 jack (J401).
•Voltages and waveforms are dc with respect to ground in playback
mode.
no mark : CD PLAY
* : Impossible to measure
•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.
J : CD PLAY (ANALOG OUT)
c : CD PLAY (OPTICAL OUT)
