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 diagrams
• 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
/ W or less unless otherwise
4
specified.
• % : indicates tolerance.
• 2 : nonflammable resistor.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REMOTE terminals.
• Voltage is dc with respect to ground under no-signal
condition.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.

F
for printed wiring boards
• X
: parts extracted from the component side.
•
: Through hole.
r
• b
: Pattern from the side which enables seeing.
(The other layer's patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B) pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
