Audioquest makes ferrite RF chokes called RF Stoppers; they come in two sizes, Junior & Regular. The chokes split into two pieces for easy attachment around AC cords & speaker cables. These should help; I thought someone mentioned that Radio Shaft even sells something similar. Use caution if you must filter around your interconnects; I experienced HF degradation doing this around Auqioquest Lapis interconnects, but it might work OK for you? You'll need to experiment, but the RF which is apparently riding into the amp along your cabling can be tamed.
Best Tube to eliminate RFI
I have narrowed down an RFI problem in my system to the amp. It is not volume sensitive but unique to the right channel (channel nearest the outside wall of our apt). I changed pre-amp tubes from chinese stock to Mullard military grade and Siemens. Listening to the local college radio station when I want to hear nothing is annoying.
Short of shielding the whole amp with a grounded copper mesh any comments on the best tubes (anti-nuclear attack?) that might mitigate this problem?

Merci a l’avance.
