[TriEmbed] Inexpensive 120V (15A) to 240V (7.5A) transformer?

[Phil Smith]

If you can find outlets close to each other whose hots (x and y) are from adjacent circuit breakers, then you could combine x,y, and g (ground) using two plugs to get 240V, although the outlets are likely only rated at 120V, 15A (14 AWG wire).  Another way of looking at it is x=+120V, y=-120V (relative to Neutral n here n ~= g except at high current draw.  Often wiring within a single residential room is from a single circuit breaker.  Interestingly, the National Electric Code (NEC) rates 10, 12, and 14 AWG wire at 15,20, and 30 amps no matter how long the wire is, analogous to the state of SC once legisilating the value of pi to be exactly three.  AWG<10 wire is not subject to this arbitrary amperage and equations for resistance and reactance are used instead.

 Hey all!
I am looking for a transformer to setup 120V up to 240V. I recall seeing a transformer company at the Hamfest last year but do not remember the name. Can anyone recommend a vendor? Does not have to be a high-end design. Is powering a charging system that corrects for variations in line voltage.
Thanks for any suggestions!
