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
and 1/4 W or less unless otherwise
specified.
·
%
: 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 taken with a VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal produc-
tion 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.
