Do you have any coax cables near your pre-amp? I had an ARC REF1 that would get noisy if I moved my tuners antenna coax to close to it. Sounded just like a tube getting noisy.
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.
