This transformer works well unde 10mA and I am not sure why Philco used this mammoth of a transformer (which did not help it) for the interstage while any 10mA half the size would do.

This is the audio output transformer, not interstage.

What little rust there was I've already removed. I suppose I could coat them with something, but the additional thickness will prevent me from getting them all back in.
