I'm having speaker wire issues, too. In another thread Holger posted a photo that shows the speaker wire plugging directly into the speaker socket in his radio.

I talked to a business in Columbus which services old radios. They said on the Town and Country radio that the speaker wires go into a clip which then plugs into the radio speaker socket.
I looked at a 55-57 Thunderbird parts website and they offer this for the little birds.

Since the little birds only had one speaker, this won?t work, but that looks along the order of what the guys in Columbus described.
Does this look familiar to anyone?
