Note on Schematic Diagram: MAIN SECTION

All capacitors are in F unless otherwise noted. pF: ∝∝ F 50 WV or less are not indicated except for electrolytics and tantalums.

All resistors are in and 1/4 W or less unless otherwise specified.

f : internal component.

Note: The components identified by mark 0or dotted line with mark 0are critical for safety.

Replace only with part number specified.

: B+ Line.

Power voltage is dc 1.5V and fed with regulated dc power supply from battery terminal.

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

no mark : PLAY

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 : Analog

J : Digital
