[NJARC] Line Conditioner?

[jimimaxi2 at comcast.net]

Hi all,
Will a Line Conditioner stop the electrical interference that I get thru my radio's speakers when I have it plugged into my wall socket. When I use battery power to listen to the same station there is virtually no noise.
I refer to the following web page as example -

Line Conditioner/AVR System Model #:LS606M

Thanks for any help
