Ok With the 5000 ohm section out of the circuit and the volume turned down do you hear any stations? If not you don't need the that 5000 ohm section in the circuit. If so clip lead in a separate 5000 ohm pot where the bad one was and adjust it till you can't hear any stations. Measure the resistances from the wiper to each end and select 2 fixed resistors that are close to those values. This is to mimic the pot. Wire in the same the clipped in pot was.

The lower you set the volume level with this clipped in pot the lower the overall sensitivity will be. That the design of the circuit so it a bit of a balancing act to get where you like it. Hopefully you don't have a very powerful station close by.
