Phono Preamp

Are you sure it is the EAR 834 that is picking up the station? Before moving it I would go to your local dealer and see if he will let you demo a couple of different ICs for your tonearm. I had that problem with a set of Kimber cables from my tonearm. Switched to a better shielded cable and that was the end of the radio station.

If it is the EAR tubes that are picking up the RFI there must be a simple way to block the radio waves without having to get a new phono stage. There must be a EE here on this forum that has the answer. How about trying something from the movies? Remember Gene Hackman in the movie, Enemy of the State? He had a cage made from chain link fencing that stopped signals from gettting in or out. What if you put chicken wire around the shelve that it sits on?
I know that it sounds stupid and probably is but, I bet the solution is something along this line. There has to be some material that you can surround the phono stage with that blocks the radio signal.
