Can hear TV or Radio station via Phono stage ???



What causes this? Most noticable during quiet passages in the music. Using a Lyra Lydian Beta, BAT VKP10, SME 20 Table...

And more importantly...how do I eleminate it? Thanks!

The really frustrating aspect of RFI is that with a quality phono stage and interconnects I have the problem. But when I use the phono section of a cheap Onkyo preamp there is no problem! Of course, the sound sucks, so I'm still experimenting, trying to find a phono stage that doesn't do this or a way to position it to eliminate the noise.
Suretyguy, try the Linn Linto. It cleaned up all the RF noise and sounds great.
Always try cheap fixes first. If all else fails, I suppose a Linn Linto would be nice! As nice a phono stage as it is, that's a rather pricey fix!

Here's something cheap and easy to try, if you are using a power strip:

1. Buy a hospital grade power strip (e.g., Wiremold)
2. Plug in components in this order, begining with the sockets closest to the power cord: power amp, preamp, CD player, other (e.g., phono stage, turntable).
I have the same problem with RF noise between a Kora Eclipse pre amp and my Music Hall MMF7 turntable. I found that shielding the interconnects work the best, but still does not completely remove RFI.

After getting fed up, I bought an ARC PH3 phono preamp. Connecting it to the line input on the Kora Eclipse, the TT is dead quiet now.
It's close to impossible to eliminate because you are using tubes. A solid-state unit would be quiet--and wouldn't sound as good.
Use the mute button on your preamp and try to reorient the phono stage to get the hum to an acceptable level. Move around cables--always with mute on preamp. Otherwise, you can get a big pop that will shut down your amp.
