specified.
• % : indicates tolerance.
• f : internal tolerance.
• C : panel designation.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal 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.
