W or less unless otherwise
specified.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 3V and fed with regulated dc power
supply from battery terminal.
•Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

•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.
