Note:
• All capacitors are in
— F unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ÿ and 1/4 W or less unless otherwise
specifi 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.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• Voltages are taken with VOM (Input impedance 10 M
: ).
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.

• The voltage and waveform of CSP (chip size package)
cannot be measured, becaise its lead layout is different
from that of conventional IC.
