I have two speakers. A single ended one for a Philco 90 with an open field coil and missing output transformer.

The one shown above is for a Philco 20 with push-pull 71A driving it. I disconnected the center tap and tied one end of the output transformer to one side of the field coil to make it compatible with my 90.
