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 

 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

).

Voltage variations may be noted due to normal production
tolerances.
