You can't repair a transformer. If it's blown you replace it.

Transformers are "repaired" ie. rewound only if either the iron is something really, really special, or the construction is so special, no manufacturer will make one for You.

I'd make a wild guess that Yours is neither .


But generally:

If the transformer is potted, there's no chance it can be repaired.

If an IE core transformer is welded, it can't be repaired either.

Usually only 1KW and up transformers are even considered for rewinding.

Sam

How do you know that? Sure it's not any of the other parts of the power supply that typically fail several hundred times more often?

Call GK.

Transformers can't be fixed. You just have to hope they still make them, or you can find OEM one's. You have slightly better odds with power transformers, rather than obscure tube output transformers.
