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-
D
dicated except for electrolytics and
tantalums.

• All resistors are in Ω and
1 / W or less un-

C310
less otherwise specified.
• C : panel designation.
R311
• U : B+ Line.
• Power voltage is dc 14.4V and fed with
regulated dc power supply from BATT and
REM terminals on CNP801. E
• 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. F
• Signal path.
F : AUDIO
For printed wiring boards.
Note:

• X : parts extracted from the compo-
nent side.
