• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM terminals.
• Voltage and waveform are dc with respect to ground un-
der no-signal condition.
• 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.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
