NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC 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.)
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Side A)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Side B)
the parts face are indicated.
• MAIN board is multi-layer printed board. However, the pat-
terns of intermediate-layer have not been included in the dia-
gram.

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

fied.
•
%
: indicates tolerance.
• C : panel designation.
Note:
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 (J401).
• Voltages and waveforms are dc with respect to ground in playback
mode.
• 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.
