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 : POWER ON � Voltages are taken with a VOM (Input impedance 10 M�). 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. � Signal path. F : TUNER
