[vcf-midatlantic] OT - 120v to 240v step up recommendations

[John Heritage]

Hey folks

I have a new Amiga PSU coming on from icomp that is 240V only.  I'm looking
for recommendations for a 120 to 240V step up transformer rated for at
least 100W (so it doesnt have to work hard).  Preferably silent. Etc.

Also what should I avoid in this space ?

P.S.  This PSU is the "CA PSU" from icomp - and not an original commodore
unit (as they are hard to find and old) nor one of the meanwell based units
on ebay that have problems with accelerated amigas.  I do have a cheap one
and while it can do my slightly expanded 1200 it's hard fail on an expanded
500.

Thanks !
