Volume control broken
You can purchase clear 2-part epoxy products at most home improvement stores. You will also need masking tape (or similar) a popsicle stick (or similar) a small piece of cardboard and a toothpick.
Mix the epoxy with the popsicle stick and apply a small amount to the exposed surface of the volume control's stem. Holding the knob in place, run a strip of tape from the top of the unit, across the knob and to the bottom.
These epoxies are very strong and fast setting. It's probably best to leave the tape for at least 8 hours but you should refer to the instructions for the epoxy you buy.
Good Luck,
BB
