Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PB
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.
