: internal component.
• U : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack (J301) .
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
[ ] : FM
< > : PB
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
• Signal path.
