quick question about an Admiral 20X12

[Tubejunke]

As rediculous as some may think this sounds you could cut the shaft off of another potentiometer with the same shaft diameter and knob mounting configuration and use J.B. Weld (quick setting) to secure the shaft sections. After the stuff is set but not too dry to manipulate I would mount a knob and turn it through its complete rotation and adjust as necessary to eliminate knob wobble. If someone really was worried about apearance issues the product can be ground or sanded where you may not even be able to tell the joint is there. Just an idea. I guess you need to find a correct knob first to see what kind of mount it has. Anyway I hope this is of some service to you. Good luck finding that knob. Start by posting ads on all the free swap forums you know of. Starting with the one on this site. There are a lot of good folks here. Someone should be able to help you out.
