Were those custom jobs, or off-the-shelf supplies (that someone stuffed into a 
box)? I don't think I've seen an off-the-shelf switcher with a 9VAC output* 
before, but Farnell, Plessey, Astec and Weir crop up all over the place in UK 
equipment...

that the user can tweak to their own spec, though.
