Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
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.
•
2
: nonflammable resistor.
• 5 : fusible resistor.
•
C
: panel designation.
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• : Pattern from the side which enables seeing.
(The other layers´ Patterns are not indicated.)
• Indication of transistor.
•

• 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 : TUNER (FM/AM)
E
: TAPE PALY (DECK A)
d : TAPE PALY (DECK B)
G : RECORD
J
: CD PALY (ANALOG OUT)
N : MIC INPUT
g : VIDEO
Note:
The components identified by mark
0 or dotted line
with mark
