So one day I the manual tune (right) audio knob stopped working. It mechanically turns, but does not change the station, or any other function. Anyone experience this? Can I pull off the knob to clean something?

Thanks all.

 

At this age, it probably needs to be repaired. Here's a link to get it done for $135. They'll test and refurbish the whole thing!

thanks...good link. Before blowing that kind of cash has anyone ever pulled off an audio knob? Is there anything to clean to fix it?
