SA-WMS145/WMSP50
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.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F
: AUDIO
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
•
: Pattern from the side which enables seeing.
Note: The components identified by mark 0 or dotted line
with mark
0
are critical for safety.
Replace only with part number specified.
