Unfortunately, one of the nicest has an interesting plastic
gear inside to couple a switch to the knob on the front panel, and the
plastic has gotten brittle over time. I've seen two of those with the
plastic disintergating. I own one of them. I would love to see a
drawing of the gear's dimensions, with the hopes that I could make a
replacement. The plug-in is too nice to consign to the trash bin.

It is a barrel (perhaps 3/4" long), with a hex hole through it,
and a set of gear teeth only about 1/8" long in the middle of it.

Don, what is the model number of that particular plug-in?
