DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
for schematic diagram:
Note:
• 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.
•
%
: indicates tolerance.
•
2
: nonflammable resistor.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM terminals.
• Voltage and waveform are dc with respect to ground un-
der no-signal condition.
• 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.

Note:
•
X
: parts extracted from the component side.
•
: Pattern from the side which enables seeing.
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
