Note on Printed Wiring Boards:
• X
: parts extracted from the component side.
•
p
: parts mounted on the conductor side.
•
b
: Pattern from the side which enables seeing.
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
1
/

W or less unless otherwise
specified.
•
C
: panel designation.
• U : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.

• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
