NOTES FOR PRINTED WIRING BOARD AND SCHEMATIC DIAGRAM
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
/
4
W or less unless otherwise
specified.
•
¢
: internal component.
•
2
: nonflammable resistor.
•
C
: panel designation.
Note on Printed Wiring Board:
•
X
: parts extracted from the component side.
•
p
: parts mounted on the conductor side.
•
b
: Pattern from the side which enables seeing.
• Indication of transistor.
•
U
: B+ Line.
•
V
: B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : VIDEO
• 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.
