specified.
•
%
: indicates tolerance.
•
f
: internal component.
•

: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
•
A
: B+ Line.

: B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
• 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.
• Circled numbers refer to waveforms.
• Signal path.
