5-4. PRINTED WIRING BOARD – LED/FILTER SECTION –
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.
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.
•
C
: panel designation.
•
U
: B+ Line.
• Powr voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REMOTE terminals.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: POWER ON
*
: Impossible to mersure
• 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.
F
: AUDIO
For printed wiring boards.
Note:
• X
: parts extracted from the component side.
