Phono stage picking up radio signals?

I am not familar with your phonostage so this reply may be redundant but if it has tubes try replacing them.

Some tubes play radio stations and others don't I don't know why but thats the way it is.

If that doesn't work then you have a grounding problem in your arm or shielding problem in your system somewhere.

One thing you can try is installing ferrite beads over the inputs of the phono. They must be inside the preamp to be effective. They don't work went put inside interconect RCA's.

Kel34,

Thanks for the response. It so happens the tube phono stage works fine (Cary PH-301), it's the solid state one that is causing problems. I am looking into ari-hell's suggestion as that is the cheapest way to go for now. If that doesn't work I'll try a pair of shielded ICs, as Nordost are not shielded. If all that doesn't work I have two more phono stages coming that I was going to compare against the Whest and if they work then the Whest is pobably out and I'll choose between the Hagerman and Decware.

Clio09: Sounds like the RFI problem was in the phono preamp. As for your question about the ground wires, yes you can connect them as you say -- just make sure the TT and the tonearm aren't electrically connected (no metal parts touching) or you will have created a ground loop.

And definitely try shielded cables.

Clio09 - Shoot James Henriot an email. He is a very nice guy who is very informative about his product. I think I have heard there was a batch that was shipped that was missing a part in the loading plugs that go into the back of the unit that was causing this radio reception/interference.

Shoot him an email with your serial # and problem, and see if perhaps you got a unit that had those issues...

good luck and keep us posted please.

Audiofankj,

I have emailed James before and he has always responded in kind. I did email him about the RFI issue and given the fact that he is 8 hours ahead of me and it's the weekend I'll look for his response Monday. Also, I plugged in the phono stage without any load resistance plugs and it still picked up a radio signal. While the plug theory makes sense I'm at a loss as to why the unit would continue to exhibit the problem without the plugs being utilized.

I have also tried to work through he dealer who I bought this unit from (used) and he was somewhat helpful, but insists it is a problem with my tonearm cable or the position of the unit. I know it is not the tonearm cable as I've done many tests, and as for position, I only have so much room to manuever and nothig has worked do far.

Hopefully James will have an answer.
