Most appliances sold in the U.S. these days can handle 130-volts without any problems. As far as incandescent light bulbs go, yes, the 120-volt bulbs sold in most places burn out in a hurry with the

Would it not be possible to use a relay in the primary to disconnect the transformer during standby?  Of course, the contacts on the relay would have to be able to "handle" the current.  This should
