I am looking for a source of a very small transformer that will supply

size is important. I need to be able to shoehorn the whole thing
inside of a double outlet box.

Bell transformers are smallish - but they put out more than 6 V AC.
If you want SMALL, a high frequency drive to a few turns on a ferrite
core it the bill well.
