Note:
The components identified by mark 0 or dotted line with mark
0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• Power voltage is dc 3 V and fed with regulated dc power supply
from battery terminal.
• Voltages are dc with respect to ground under no-signal conditions.
no mark : PLAY
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production toler
ances.
• Circled numbers refer to waveforms.
