: nonfl ammable resistor.
• C : panel designation.
• Note for Printed Wiring Boards and Schematic Diagrams
• A : B+ Line.
• B : B– Line.
• H : Adjustment for repair.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• 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.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
