Power voltage is dc 4.5 V and fed with regulated dc power supply from external power voltage jack.

Voltage and waveforms are dc with respect to ground under no-signal conditions.

: Impossible to measure

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.
