RFI in tube system

Hi Folks,
I need help. I recently set up my tube system in my new house and everything was great for a couple of months. Then I started to pick up significant RFI. I can hear a muted radio station coming through my system and static interference. Driving me crazy.

I've been playing around with cables, equipement, etc and found the following: My Shanling SACD player has output levels, so I bypassed the preamp and hooked my CDP directly into my amps. RFI was gone. So it seems that the preamp is the problem. I've switched out my interconnects and power cords and there's no appreciable difference. I've also tried using another outlet with no improvement.

I'm not sure what I'm doing here as I'm not very technologically savvy, so any advice would be appreciated. I've read here about power conditioners. Would they help? Or RFI Filters on my interconnects & power cord? Or is this going to be an expensive hit-or-miss process.

Thanks in advance for any advice.

Thanks for all your helpful advice everyone - and sorry for my delayed response. (My job popped a surprise worktrip on me and I've been out of town for a couple of days.)

Mrtennis, I'll pm you about those rfi chokes. Woudl like to give them a try though I'm using Audio Metallurgys and need to figure out if they'll fit around them.

I'll also try to further isolate the problem as suggested when I get home tonight. In the meantime, I was looking at a PS Audio Duet (I'm on a budget here!) Does anyoen thing that might help reduce the rfi problem?

Thanks again!!!
