These are super easy to replace and readily available for cheap and most are deteriorating if they sit unused for some time.

It looks like a squareish porcelain socket. The bulb plugs into this socket via pins and the pins can shear easily.
I've read in other forums that the ceramic piece can be a problem. I'll check that as well. Thanks!
