The small switcher in DEC's TK50 tabletop box does exactly that. I got
to sort through a pallet-load of the things once, and got to keep
several that looked repairable. Well, they were, but at least two had
to be repaired twice because I forgot to hook up the minimum load board
that the TK50-AA box usually has.
However, I have to admit that's the only time I've been bitten in that
way, and the PSU in a BA23 certainly shouldn't get too upset by a
no-load situation. I'd guess it's just lost a mains filter cap.
