TMI+10Guy13 is quite a character
Hi Guy,Unshielded wires at the headshell can pick up noise or RF. Braiding those wires tends to reject noise, but you don't want to stress the connections. Probably nothing to worry about, but I can't tell how tight it is.So, you hooked up an antenna ground wire from your phono stage ground to the AC outlet and now you're listening to the radio and a record at the same time? I suspect the reason it wasn't a problem in the last house is due to chance. You know what they say, "Location, Location, Location".Chances are, if you get rid of that wire you'll be fine. There is no easy way to connect a ground wire to your Rega arm AFAIK. The ground is in one of the channel grounds and it, in turn should be connect to the ground inside your phono preamp. neo
TMI but implicitly. I will let it slide. I mean she may have called him because the TV remote was stuck. Guy, we don't need to know anymore about what goes on in your bedroom.
I hate to say this but I used to own a Soundcraftsman pre-amp that picked up radio signals through the phono section. Tried several turntables and, always, in the background was the local Christian broadcasting station. Faint but audible. I moved 13 miles, and no difference. Apparently Soundcraftsman didn't use blocking caps in the circuit. Finally sold it to a guy at work. He has three turntables and it still gets radio. I has to come through the jacks, as there are no vents in the cabinet. He also has a Bellari that is dead quiet.Hope it is your ground arrangement causing the problem.
Hi jtwrace.You american guys with all your abbreviations.What's the meaning of TMI ? ? ? Guy 13I hope it's a compliment.
TMI = Too Much Information

Hi jtwraceI may sound like a playboy, but I sure don't look like one. Guy 13
Hi neo.I just finish doing more tests.The problem must come from the cartridge/arm, because if I disconnect the interconnect cables from the phono the music, the FM music that is, stop.With a jumper wire with alligator clips at both ends I connect them to the ground lug of the phono and I tried to clip it to different parts of the arm and nothing happen.I have to conclude that the Bellari phono is O.K. and that the Rega arm is not O.K.I will leave it like that for now...

Hi Guy,Did you get rid of that red ground wire going from your Bellari to the wall outlet? If not, try disconnecting it and see what happens. It's worth a shot anyway. It could be that the arm is the problem and the red wire is making it worse. I'd rather not elaborate on your options until you try this.neo
Killing the arm might be a tempting release of frustration, but life goes on and the Rega still has value. The obvious solution is to rewire or replace the arm/table.Do you have a friend nearby with a functioning record player you could borrow to test your system? Chances are, the arm wiring is the problem but it would be nice to know beforehand if that is a satisfactory solution. There's a cottage industry for modifying Rega arms. Rewiring kits are sold on the net. If that's not an option, then you could sell the table and replace it.Sorry there's no easy solution. Don't you have a tech that can do the job? If so, that might be the least expensive fix. It would be good if you could test the system first.neo
Get a volt/ohm meter and do a continuity check on all the wires, from cartridge to RCAs. If you find one of the shield wires is bad, you can "share" the shield wire that is good for both channels by making a bridge between the two wires at the cartridge. In other words, sum up both (-) terminals on the cartridge.Almost all preamps sum these 2 leads anyway.
