go to this link. Digital Theater Forum I asked the same question and BruceK there explain in detail about how to DIY this conversion. you'll get a balance 220V! 110V- and 110V+. and a ground no neutral. no hum problem! I have all of my component modified to use 220V. good luck
220 Volt Ciruits
Has anyone run their audio equipment off of a 220 volt circuit (like appliances use) either directly or using some sort of splitter or transformer? I am hoping to be able o use an unused appliance outlet in my new apartment as a dedicated line for my audio system. Any thoughts?
