The plastic gear on my original radio is partially worn not allowing the knob to move smoothly across the dial. I know that Hurtle_11 says there is no repair for this. It is not that I am questioning him. But it seems that there has to be a repair for this. Any place to get the part? If so can it be fixed by an average person? If not who can fix it? Hopefully someone in GA. I am not sure it is worth sending across the nation. It would just be nice to repair it.
