W or less unless otherwise
specified.
•
1
: fusible resistor.
•
C
: panel designation.
• 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.
no mark : FM
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
