• A : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : TUNER (FM/AM)
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
