NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
•
X
: parts extracted from the component side.
•
f
: internal component.
•
b
: Pattern from the side which enables seeing.
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Side B)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Side A)
the parts face are indicated.
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.
•
2
: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
•
U
: B+ Line.
•
V
: B– Line.
•
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.
