Phono Preamp acting as a Tuner. Help!

I don't think its your phone preamp. Rather its your phono cartridge and the cable between it and the pre that are acting like an antenna. Move the cable around and if the distance is short coil the cable. Moving the coil so its not facing the direction of the signal should minimize the broadcast. One other thing. Disconnect the phono cable and listen to the pre with out any input. If you still hear the radio, its coming through your AC power. The most likely culpret in this scenario, assuming your system works properly, is a moving coil cartridge. Those little coils are reasonably good radio antennas. Try taking a sheet of tinfoil and wrap it around the cartridge. Don't help much if you are trying to play a record but if the broadcast goes away, there is your problem. The fix could mean rotating your turntable 90 degrees(like the cable). Good luck.

I concur with Keis, it's the cantilever/cartridge motor, being amplified by the phono stage. Mine has picked up what seems to be an AM Cuban American station. I had to kill that dictator down there, just to get them to shut up...haven't had any problems after that.

It should be parts upstream of the phono stage but if covering it with you hand worked, maybe that is worth investigating. My suggestion is get some lead shot or a sheet of lead and put it over your phono stage. That should definately stop any radio signals from going into the phono stage itself.

I have the same problem, but do not have any phono in the system. Just started when I moved into a new house, so I suspected the AC. Using a Levinson 380S and Bryston 7Bs. Any ideas? Thanks!
