THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS
AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
Note:
• 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.
• % : indicates tolerance.
•
2
: nonflammable resistor.

•
A
: B+ Line.
• B : B– Line.
• Total current is measured with no-signal condition.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM terminals.
• Voltage is dc with respect to ground under no-signal
condition.
• 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.
