Also a saturating transformer gets hot! Some transformers only have a problem on 50Hz vs 60Hz when on load.
As Jeffrey says, use minimum mains voltage, which can even be 100V (series antiphase 10V or 20V transformer on primary is better than a resistor).
Some gear has well spec'd transformers and is OK.
