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 

 and

W or less unless otherwise

specified.

%

: indicates tolerance.

2

: nonflammable resistor.

A

: B+ Line.

B

: B– Line.

• 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

).

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.
