Note:
• All capacitors are in
µ
F unless otherwise noted. pF:
µµ
F 50WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in
Ω
and 1/4W or less unless otherwise specified.
•
B+
: B+ Line.
•
B–
: B– Line.
•
: adjustment for repair.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : FM TUNER
• Voltages are taken with a VOM (Input impedance 10M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
