• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
• 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.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
