That is one big transformer! I can't imagine why you'd want to use such a thing.

If it runs hot it must have a shorted turn. If you have a wattmeter, measure the power draw with no load. Obviously it's high or you wouldn't have that much heat.

I submit that the thing is defective.

AndrewT, looking for a compendium of troubleshooting tidbits - well just ask me. I have more information in my head than even I can believe. Seriously, these things require a certain talent to invent. For instance, I invented (I am sure I'm not the first) a method of discovering where a break is in a shielded cable. It's usually at one end but my method finds it without cutting or piercing, within an inch or so.

It also helps that I have a degree in Electrical Engineering, have been a radio amateur for over 60 years, and owned an electronics repair shop for many years.

to dramatically reduce the core loss connect the transformer as 240v to 240v and use on 120v.
this makes a lot of sense if you are not using the full 5kva rating of your isolation traffo..

is your line 120 or is it 125?

dropping the line 10% will drastically cut core losses.

Yes, it will run cooler and may benifit your system having your amp on Balaned power.
