ICF-C630
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
Common Note on Schematic Diagram:
• 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
specified.
• : internal component.
f
• C : panel designation.
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 4.5V and fed with regulated dc power
supply from external power voltage jack.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
no mark : FM
( ) : AM
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F
: FM
f
: AM
Common Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• : internal component.
f
•
: Pattern from the side which enables seeing.
