Thanks for the plug Les! I'd like to add that the transformers
I use are UR (USA), CSA (Canada), and CE (Europe) qualified.

Further, they are 60Hz (but also 50Hz rated for Europe, which
is actually a tougher spec to meet, but it means at 60Hz the
stress is less) and I can be wire the kit for either
120VAC input or 220/240VAC on request.
