Well if your outlets are inverted you can switch the wires around. Also you may as well put in some new outlets, commercial ones are under 5 bucks each. It's easy to do it you can operate a screwdriver. Be sure to switch off the power first! You can get good power conditioners made by Oneac and Powervar off of Ebay for relatively cheap. You still won't have a ground but otherwise you should be ok.
Clean power & ground issue?
I have a serious ground problem in my home. I have tested the outlets & they all show ungrounded & inverted. It's obvious that whoever did the electrical work in my home missed a few steps. Can I overcome the ground issue with one of the power conditioners on the market? I know this is holding my system back & want to take the next step. Short of rewiring my house or getting an electrician in to run a new line what else can I do?
