The Fine Things are Always Hand Made

Thought I'd start a new thread as this relates to a different problem. While checking transformers, I found the interstage transformer between the 2 6J5s and the 2 6L6s has a problem. I can't believe ALL windings are shot, but the only place I get continuity (1KΩ) is between the center tap of the primary, and one lead to the primary.Nothing to the other lead.  No continuity at all between any windings of the secondary. There is no evidence of it heating up at all. I removed the transformer, but before I start digging in the tar, I thought I'd touch base here. I've run across a lot of transformers with one open winding, but never with ALL open windings. Thoughts? Not sure how to post a pic here.

In general, Scott transformers from the late 30s are very reliable. I did have one of these with one open primary side, but even with earlier models, an open secondary (low voltage/low current) is really unheard of. I suspect something else might have happened...lightning strike on the power line (check power xformer!!) or maybe a horribly shorted 6L6....

These are tougher to replace, they have the separate secondary windings, not a typical interstage. I'd have to dig to see if I have a replacement somewhere around here.

Power xformer is good, and so are both chokes. I rechecked the windings several times, with the same results. I really appreciate you looking for a replacement for me. I think I'll go ahead and see if I can "de-tar" it. I still can't see any evidence of what could have caused the problem.
