• C : panel designation.
• A : B+ Line.
• Power voltage is dc 12 V and fed with regulated dc power
supply from connector (CN500).
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
no mark : Power ON
• 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.
