the pads had worn out on the volume control, so I took it apart, and cut
the rubber pad between the 4th and 5th row, and flipped around. This moved "bad" buttons to key's I don't use. So, I should now be able to get another 15 years out of it hopefully. But If I can get another one I probably will. Found several Carver remotes on Ebay, but none of this one yet.
