It worked great as a replacement audio inter-stage transformer for my RCA Superette R-7 that uses a push-pull circuit. The original transformer was potted in tar in a can on top of the chassis. I left the old one in place and mounted this nearby on the outside of the chassis. I'm very happy with it.

Customer wanted his Philco 95 to look original. The audio interstage transformer was open. This transformer easily fit into the original Philco shell and works perfect. - September 9th, 2017

This transformer fits perfectly into the original can for the 2nd Stage Audio coupling transformer in Atwater Kent models 42, 56, and others that use a smaller can. It also works very well and at a great price.

Used for coffin style Atwater Kent Radios, excellent match, fits in can (side ways), works like a charm. Good price too

A great interstate transformer, I used several of these to rebuild old radios.
They work just fine.
