Ideally, I would like:

0-5 Amps
Linear rather than SMPS
230/240VAC

The last three are not deal-breakers though. I've seen a few on eBay,
but am not certain about quality. Like this:

It would be nice to find one here in Australia, but 30-0-30 seems to be
the limit for the popular choices.

I would want my bench power supply to be as quiet as possible. Who cares about efficiency when you're designing and powering up a prototype. You may wind up with a switcher in the final design but I would definitely not get a switcher frr new product evaluation. Lenny.
