Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 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 10MΩ).
Voltage variations may be noted due to normal production
tolerances.
