Note on Schematic Diagram:
•
All capacitors are in
µ
F unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
•
All resistors are in
Ω
and 1 /
4
W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
•
A : B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
•
Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
•
Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER (FM/AM)
(
) : DVD PLAY
∗
: Impossible to measure
•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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 : DVD/CD PLAY (AUDIO)
