AMX Radio Knobs

1. Check to see if the spring metal clip is loose in the knob and/or the clip is flattened. If so, sometimes you can remove the clip with tweezers. Squeeze the clip and slowly work it out. ( I will say, this causes more damages 50% of the time. If you get the clip out and can spread the clip, reinstall and the problem is corrected

2. Carefully inspect the knob for damages down inside where the radio knob shaft would rest. Many times you will find damages in this area. Usually not repairable!

Now for some easy fixes. If you think the clip is flattened and can not be removed try these remedies

1. Cut a sliver the width of the clip from a matchbook cover. Side the cardboard into the opening next the clip and slide onto the radio knob shaft. This is not a strong repair, if you don't use the radio and its for static display, the cardboard is just enough resistance to keep the knob from falling off.

2. You can glue the knob on. You will need to experiment on which glue works best. I like to start with mild to strong. The reason I say experiment, there are plenty of glues that will permanently glue the knob back on, but you might need to take the radio out of the car again. A weak glue will allow you to remove the knob with a little persuasion at a later date. I have started with Elmers glue (knob stayed on for about a week - I was using the radio everyday). Then I tried some automotive trim adhesive glue which lasted about 3 months. I kept with the trim adhesive and just started being very gentle with turning the knob. That radio knob stayed attached for about two years before I had to clean the old glue out and replace with new glue

3. Replace the radio knob

Just my two cents worth.
