Ferrite install on appliances AC cable

I have ferrite clamps on everything not audio. I have an assortment of press closed capture type and plain long tubes 1" long abut 1/2 " outer diameter.. I can use the tubes on any zip cord. I fold the zip up into the tube and out, bending it over to fit around the other end between the entering and exiting wire. pull tight, wrap with Teflon plumber's tape. Two on each cord, one at each end. Lamps, air cleaners. refrigerator.  
Just to mention even $3000  audiophile powercords from Cardas have a ferrite device included in the design..

Until I put a Ferrite core on my antenna lead to my tuner, my tuner was unlistenable with my kitchen lights on. My kitchen lights are all LEDs and must be putting out a lot of junk. 

elizabeth, It's a shame that I can not see a photo to capture your idea.
