• Refer to page 11 for Circuit Boards Location.
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this 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 specified.
Note on Printed Wiring Boards:
•
X
: parts extracted from the component side.
•
W
: indicates side identified with part number.
•
b
: Pattern from the side which enables seeing.
• Power voltage is dc 9 V and fed with regulated dc power supply
• Voltages is dc with respect to ground under no-signal (detuned)
) : MW/SW
((
)) : PB
<< >>: REC
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal production toler-
ances.
• Signal path.
