Parts on the parts face side seen from   
the pattern face are indicated.
Parts on the pattern face side seen from   
the parts face are indicated.

Note:
•  All capacitors are in 

μF 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 

specifi ed.

component.

• 

2 : nonfl ammable 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
•  Voltages are taken with a VOM (Input impedance 10 M

Ω).

  Voltage variations may be noted due to normal production 

tolerances.
