Note for Printed Wiring Boards and Schematic Diagrams
•
MAIN and DSP boards are multi-layer printed board.
However, the patterns of intermediate-layer have not been in-
cluded in diagram.

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

/
4
W or less unless otherwise
specified.
•
f
: internal component.
•
2
: nonflammable resistor.
•
5
: fusible resistor.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
•
Voltages and waveforms are dc with respect to ground
under no-signal conditions.

•
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.
