Any good electrical supply house can get autotransformers. I like Tristate
Electrical Supply. You can sometimes get them surplus at C&H Sales in
Pasadena but they usually don't come in NEMA boxes and will require some
mounting work if you get them that way.

IF you have a real transformer instead of a fancy switching supply to
knock the voltage down, yes. Note that if you dim low-voltage halogens,
you will radically reduce your bulb life (even if you crank them up to
full brightness for a few minutes every few hours to get the halogen cycle
going again).
