: internal component.
• U : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM
( ) : MW
< > : SW1,SW2
Note:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
