W or less unless otherwise
specified.
•
¢
: internal component.
•
C
: panel designation.
Note on Printed Wiring Boards:
•
X
: parts extracted from the component side.
•
: Pattern from the side which enables seeing.
• Indication of transistor.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• 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.
