AC Regenerator

Your fine running tube equipment, tape decks, turntables and electric trains for the matter on a PS Audio unit. Just don't put it on any of the wave options and keep it on 60 hz. 
  About bad electricity. I downloaded one of the free apps for the measurement. I'm of electromagnetic radiation. It went way into the red placing it near a motorola walkie talkie. Same thing happened near a hairdryer. I got it to measure the electronic field on a tape head to see if. It needed demagnetized but couldn't find anything. All the ill effects of electricity is a new frontier. Imagine if used properly in a different way it could also heal!

They have already stumbled accross the anti-depressive effects of a brain MRI scan!!

You need to use a magnetometer to measure that.

I thank you all, and now specially to "hemigreg", who brings us a very important theme with several comprehensivenesses, of great relevance in which I very much believe.
But I think that my solution, at this moment, involves  cost and practicality of application.
An then I ask you : 

Where can I find good audio stores in New York City, or others cities where I can find  trustworthy used AC regenerators ???
