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.

• WAVEFORMS
Note on Schematic Diagram:
• All capacitors are in
µ
F unless otherwise noted. pF:
µµ
F 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in
Ω
and

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 terminals (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 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.
