I think Take 5 Audio in Canada has the Vampire stuff, at least last time I looked. Otherwise I'd go with Neotech too, no need ot go any bigger than 20ha in my world. I swear I've sent something like this to Hong Kong before...
Back to the IEC - Marc, I'm not assuming anything, you have to use external jumpers to connect G and H to something and logically it looks like B and F are how they intended it to be (from the schematic). But perhaps that's where my fail starts regarding this? One more thing, if you look at the third page of the data sheet you get a back panel view of where all the connections are and how they layout.
