Ok, have finally found something workable, if not cheap.
There's a company that makes isolated step down transformers using
toroidal transformers. No iron core to get hot!


Sigh. That 'Toroid' is wound from steel tape. You can't make a
decent 50 or 60 Hz transformer without it. the loses would be sky high,
and it would go up in flames from the losses. The advantage to toroidal
transformers is lower losses of the magnetic fields, which makes them
more efficient, and less likely to affect other equipment with a stray
alternating magnetic field.
