Balanced Power

Karls, yes, that is true. However, in keeping with the original poster's question, I was addressing the house wiring/service panel only.

Also, since I've been wanting to do this only for my amp, thus leaving it at 230 volts and converting the amp to 230v, I had no need myself to research down-converters for 115v. So in my illustrations above, I stayed away from what I did not know.

And in my posting above where I describe how one can obtain balanced power at the service panel, at least one poster here responded by stating what I described could not be done. Unless of course, one were to use that line for an oven or clothes dryer.

At least some of us know that statement is simply untrue.

Thank you all for your answers. My request was for a Do-it-yourself type of project, without involving expensive transformers. (I am positive that I have read this approach in a past issue of Stereophile if memory serves me right.)
The changing of the electrical panel sounds more like a project that I would be inclined to install first.

To try to clear up the confusion here:
Normal house service is wired 240v balanced, meaning two 120v legs in opposite phase plus a neutral wire. The two 120v legs alternate in the panel from one breaker slot to the next in a vertical direction, on both sides of the panel. Any double circuit breaker (just like your clothes dryer uses) will give you 240v balanced. On the other hand, all 120v is taken from one or the other 120v legs plus the neutral wire. Half of your house is wired from one 120v leg, and half from the other, in a random fashion determined by the guy who wired up the panel. There is no way on heaven or earth to get balanced 120v (meaning +/- 60v with neutral) out of this setup by simple wiring changes. You must use a transformer. I hope this helps.

Karls,
This does help. I believe you are right and your explanation is plenty clear, thanks.
