DIAGRAMS
For Schematic Diagrams.
Note:
• All capacitors are in
μ
F unless otherwise noted. (p: pF) 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 fi ed.
•
f
: internal component.
•
C
: panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
( ) : AM or MW
[ ] : LW
< > : CD PLAY
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
