50 WV or less are not indicated except for electrolytics
and tantalums.
All resistors are in

W or less unless otherwise
specified.
f
: internal component.
5
: fusible resistor.
2
: nonflammable resistor.
C
: panel designation.
Note: The components identified by mark 
0
 or dotted line
with mark 
0
 are critical for safety.
Replace only with part number specified.
A
: B+ Line.
B
: B– Line.
Voltages are dc with respect to ground under no-signal
conditions.
(When measuring circuit that used “V-GND” of the MAIN
DIF board, ground it from CNP5202 pin 
3
 on the MAIN
DIF board.)
no mark : TUNER
: Impossible to measure
Voltages are taken with a VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal produc-
tion tolerances.
Signal path.
F
: AUDIO (ANALOG)
J
: AUDIO (DIGITAL)
Note on Printed Wiring Board:
X
: parts extracted from the component side.
Y
: parts extracted from the conductor side.
f
: internal component.
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side:
Parts on the pattern face side seen from
(Conductor Side)
