Bae 312a hot transformer

[Richard Crowley]

Which transformer is getting hot? The input (round) or output (rectangle)?
Do you have more than one of these preamp units? Can you swap the amplifier module?

Thanks for answer , the hot transformer is the rectangle, and I dont have other bae unit, I just have a shadowhills gamma preamp,

It seems likely that something has failed in the amplifier module and is likely putting large amounts of DC current through the primary winding, making it heat up. This is dangerous for the transformer and you should get it repaired before the transformer is damaged. The most likely repair would be to replace the amplifier module. Fortunately, that is a plug-in that you can do yourself (after getting a new replacement).
