Replace only with part number specified.
•U : B+ Line.
•Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords.
•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 tolerances.
•Circled numbers refer to waveforms.
•Signal path.
F : FM f : AM
J : CD
for printed wiring boards:
•X: parts extracted from the component side.
•Y: parts extracted from the conductor side.
•a : Through hole.
•
: Pattern from the side which enables seeing.
