All resistors are in and 1/4 W or less unless otherwisespecified.%: indicates tolerance. C : panel designation. U : B+ Line. Power voltage is dc 1.5 V and fed with regulated dc powersupply from battery terminal. Voltages and waveforms are dc with respect to groundunder no-signal (detuned) conditions. Voltages are taken with a VOM (Input impedance 10 M).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. Signal path.F: MICRef.
