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

/
4
W or less unless otherwise
specified.
•
¢
: internal component.
•
2
: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
•
U
: B+ Line.
•
V
: B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : AUDIO
• 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.
F
: AUDIO
• Abbreviation
CND
: Canadian model
• Circuit Boards Location
Note:
The components identi-
fied by mark

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