i've been googling for ages but cannot find a mains transformer that
could run a 250 Watt 24 Volt halogen bulb.   It's for an 1950s slide
projector.

Any thoughts were to look, or why such beasts only seem to go up to 60
Watts?

thanks

This any good?

ITYF they're going to be in the 60-70 quid region for 250VA or thereabouts.

For more choices, google:

250va 24v transformer

That's great thank you.    I googled for Watts and W but not for VA.

You must have been looking for the wrong spec.

250 VA 0-12 0-12 transformers are a stock item with most electronics
suppliers - Farnell, RS etc. You series the secondary windings to get the
24 volts. Costs about 20 quid for a toroidal.
