I think some of you may be confused. 220 from a appliance outlet (clothes dryer plug), is actually two 110 volt runs, as is the feed to your main breaker box. If you split the 220 into two runs (this is NOT a transformer, but a wiring thing), you risk no damage to your equipment. There are a few pieces of US stereo gear that are designed to run on 110 and 220, this usually requires circuitry changes by the manufacturer. In any event, if the piece you wish to power from the appliance plug is NOT 220, the conversion box I mentioned, (the first posting on this thread), will provide at least two dedicated 110V plugs. Since the breaker for "dryers" is usually large, a duplex of 110V outlets per side of the 110V run would not be a strain on this electrical drop. If you cannot find the data sheet I mentioned (printed by General Electric), then call or hire an electrician to build the box that converts this safely. Really, it is not a big deal to wire it, I have done this myself, but It has been so long, I am afraid I might give incorrect wiring advise on the procedures to safely do this.
