•U : B+ Line.
•V : B– Line.
•H : adjustment for repair.
•Voltages and waveforms are dc with respect to ground under
No mark : FM
•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.
•Waveforms are taken with a oscilloscope.
•Circled numbers refer to waveforms.
•Signal path. F : FM J : CD g : VIDEO I : PHONO
