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

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.

The first thing to check is the ground. Make sure you are properly grounded.

Second is the connection.

I agree with other posters that location and connection is first step. I have cured my RFI by tightening connection by just jamming the cables in harder into the integrated amp I'm using....then securing the ground (it had popped out during the process and I couldn't figure out why the tightening was no longer working as it had before).

To me it comes down to flawed design of certain TTs. My stuff is vintage. They probably learned to fix over time.

Ground, ground, ground. Check the ground. Then make sure both tonearm is grounded to phono preamp and then your table plinth (bearing) is grounded to something. If you do these two things, 99% of RF problems will be a distant memory.

If you have a tube amps - replacing the power tubes may be just the ticket as this was the case for me. I had three plus year old New Sensor Mullard EL34's in my int amp and once I dropped in new a new set of matched quads WHAMO no more RF issue.
