I did an extensive rebuild of a Zenith 6S524 some time ago. The owner had complained about noise in his home so I added the filter to the inside of the back apron of the chassis. I kept the leads short from the power entrance to the filter. FWIR it was a 3 amp Cornell single pi section with a common mode choke in a completely sealed can. It worked very well at reducing the line noise.
