W or less unless otherwise
specified.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• H : adjustment for repair.
• A : B+ Line.
• B : B– Line.
•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.
