• f : internal component.
• 2 : nonflammable resistor.
• C : panel designation.
• A : B+ Line.
•Voltages 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 production
tolerances.
•Waveforms are taken with a oscilloscope.
