Hi Bob,

Yes, the red terminal is where you should connect the antenna. If you attach a 5-10 foot wire, that should be sufficient to receive a strong local station.

Another thing to check would be the AVC resistor (R44). This should be a 1meg resistor. Did you replace this resistor? If it was open or if it's value is significantly higher, then the gain in the first stages will be reduced.
