yea, i was talking about a dedicated PSU, not just a x-former. i think that's your best bet. over here in the states, i believe mouser.com sells many different varieties. not sure what you've got across the pond-maybe someone else can weigh in?
ok, now i see your voltage concerns. that makes sense.

Right - but on a transformer, the two are linked, because of the
resisistance of its windings.
Normally, you have a full-load voltage specified, and an off-load voltage.
If you're running it at a light load, you're closer to the off-load spec
than the full-load spec.
But to get back to practical matters, I've looked up the specs for a random
picked 500VA transformer. Full-load voltage and off-load voltage only differ
by 4% - we certainly can live with ∗that∗.

Wait a minute - were you talking about a regulated AC PSU, and not a simple
transformer?
With active electronics inside that regulates the amplitude of the AC output
? (But these have other problems.)
