Note on Printed Wiring Board:
•
X
: parts extracted from the component side.
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
Note on Schematic Diagrams:
• 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.
• ¢ : internal component.
•
2
: nonflammable resistor.
• C : panel designation.
• H : adjustment for repair.
•
U
: B+ Line.
• Power voltage is dc 12 V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

).
Voltage variations may be noted due to normal produc-
tion tolerances.
