NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
• Waveforms
•
A
: B+ Line.
• Total current is measured with CD installed.
• Power voltage is dc 4.5 V and fed with regulated dc power supply
from DC IN jack.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : CD PLAY
*
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
