I acquired a broken piece of vintage gear in which the transformer has one primary and many secondaries. Examining the crispy remains of the transformer, I found that one of the secondaries shorted to the primary. All the other secondaries appear to remain isolated from everything else. The transformer isn't easily replaced, and with all the secondaries, I'm reluctant to try to rewind it. I'm considering adding an additional transformer to replace the one damaged secondary--my question is would I be able to safely get away with using the damaged transformer leaving the one shorted secondary out of circuit?
