specified.
•
U
: B+ Line.
• Power voltage is dc 6 V and fed with regulated dc power
supply from external power voltage jack (J402).
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : WFM/AM/NFM
(

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