W or less unless otherwise
specified.
•
¢
: internal component.
•
C
: panel designation.
•
U
: B+ Line.
•
H
: adjustment for repair.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.
• Voltages and waveforms are dc with respect to ground in
service mode.

).
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.
