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.
• ¢ : internal component.
• C : panel designation.
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• ¢ : internal component.
• b : Pattern from the side which enables seeing.
• : Solder bridge.
• Indication of transistor.
Note:
The components identi-
fied by mark
! or dotted
line with mark ! are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque

• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: PLAY
• Voltages are taken with a VOM (Input impedance 10 M Ω ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
J : CD
c : digital out
• Abbreviation
AED : North European
AUS : Australian model.
CND : Canadian model.
E2
: 120 V AC Area in E model.
E3 : 240 V AC Area in E model.
SP : Singapore model.
