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 speci-
fied.
•
¢
: internal component.
•
C
: panel designation
•
U
: B+ Line.
•
V
: B– Line.
• Voltages and waveforms are dc with respect to ground under
no-signal (detuned) conditions.
no mark : PLAY
•
: Impossible to measure.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production tol-
erances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tol-
erances.
• Circled numbers refer to waveforms.
• Signal path.
J
: CD
c
: digital out
For printed wiring boards.
Note:
•
X
: parts extracted from the component side.
•
b
: Pattern from the side which enables seeing.
Note:
The components identified by mark
!
or dotted line with
mark
!
are critical for safety.
Replace only with part number specified.
