Note:
• All capacitors are in
μ
F 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
speci
fi
ed.
•
f
:
internal
component.
•
C
: panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•
A
: B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
*
: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

Note:
•
X
: Parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
f
:
internal
component.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Note:
The components identi-
fi
ed by mark
0
or dotted
line with mark

are criti-
cal for safety.
Replace only with part
number speci
fi
ed.
Note:
Les composants identi
