Voltages and waveforms are dc with respect to ground in playback mode.

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.
