For Schematic Diagrams.
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
specified.
• %
: indicates tolerance.
•
f
: internal component.
•
2
: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
• Voltages and waveforms are dc with respect to ground un-
der 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 production
tolerances.
• Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
