Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
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.
•
2
: nonflammable resistor.
•
C
: panel designation.
Note:
The components identi-
fied by mark
0
or dotted
line with mark
0
are criti-
cal 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
piéce portant le numéro
spécifié.
•
A
: B+ Line.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.

: LINE
c
: DIGITAL AUDIO (OPTICAL)
J
: DIGITAL AUDIO (COAXIAL)
