Several months ago I "rescued" a Philco Model 70 from a thrift store. I'm in the process of collecting a speaker, output transformer and other missing components.

A few days ago I purchased a Model 70 speaker with attached output transformer. Unfortunately, the field coil and primary winding of the output transformer appear to be open. (For guidance I'm using Ron's informative Tech Section article titled "The Speaker Problem in Early Philco Cathedrals.")

Has anyone repaired or rewound one of these field coils? I understand the center of the "pot" is pressed into the frame. I'd appreciate any advice (e.g., disassembly, technique).

A post on the Phorum states that replacement output transformers are available from Hammond. I'd prefer an original. As with the field coil, I'd welcome any advice on repairing or rewinding these transforms. Alternatively, has anyone used an individual or business that performs these services? Ron's Philco Resources mentions Heyboer Transformers. Is this cost effective or should I renew my search for a good used speaker and output transformer?

Thanks,
