50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/
specified.
4
W or less unless otherwise
• % : indicates tolerance.
f
•
: internal component.
• 2 : nonflammable resistor.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V terminal (CN901).
• Voltages are tak en with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Signal path.
F : AUDIO
For printed wiring boards
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
