RF noise on c-j P-10 pre-amp

129.128.181.153

Please help if there is any way to eliminate RF noise in my system. The radio noise is quite audible even 12 feet away or at listening position and from every input source. I tried to replace/swap ic between source-preamp-power amp, it didn't work. I put RF blocker/cap (Cardas) on all open RCA input, nosie floor is lowered, but still loud enough to hear. I also tried to use cheater plug to unground all pc, it didn't help.
Somebody mentioned c-j P-10 is quite prone/sensitive to RF due to 6GK5 it uses. Builing a metal shield case around the P-10 might help?
