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 in-
dicated except for electrolytics and
tantalums.
• All resistors are in Ωand 1/4W or less un-
less otherwise specified.
•C: panel designation.
•U: B+ Line.
• Power voltage is dc 14.4V and fed with
regulated dc power supply from ACC and
BATT cords.
• Voltages and waveforms are dc with re-
spect to ground under no-signal condi-
tions.
no mark : POWER ON
*: Impossible to measure
• Voltage are taken with a VOM (Input im-
pedance 10 MΩ).
Voltage variations may be noted due to
normal production tolerances.
• Signal path.
F: AUDIO
For printed wiring boards.
Note:
•X:partsextractedfromthe compo-
nent side.
