I found this amazing anyway,,,I have a program that runs on my computer that puts out a 60 hz sign wave through the computers speakers,,i disconnected the computer speakers and took the two wires and connected them to a transformer about the size of my fist,,i then connected the other end of the transformer to my radio power cord,,the same cord that plugs into a 110 v plugin,,and the radio works,,on am and fm,,and can be turned up loud,,just as if i had been plugged it into a 110 v outlet..So I figure the comps speakers cant be putting out no more then maybe 5 or 6 or so volts and are pulsing at 60 hz because of the program running them and thats even less then a 9 volt battery,,and if you connect a 9 volt battery to the power cord it will not power the radio nor will connecting just the speakers to the coil playing any music power the radio ,,yet doing it the way I mentioned above pulsed at 60 hz it powers a 110v radio from its 110 v power cord..Anyway I thought it was amazing...
