NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
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

W or less unless otherwise
specified.
•
f
: internal component.
•
5
: fusible resistor.
•
C
: panel designation.

•
H
: adjustment for repair.
• 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:
The components identi-
fied by mark
0
or dotted
line with mark

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