Note on Schematic Diagram:
•
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.
•
f : internal component.
•
2
: nonflammable resistor.
•
C : panel designation.
•
A : B+ Line.
•
B
: B– Line.
•
Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : TUNER (FM/AM)
(

•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
