Thanks, thats helpful, excuse my ignorance, but what are ferrite beads and where might you find them, a harware shop?
Radio interference on my phono stage
Any suggestions guys, I have a set up I enjoy, but am troubled at times by picking up foreign radio stations(I live in the UK)
System(vinyl bit): Origin Live Resolution/Illustrious
Koetsu Rosewood signature
Clearaudio Reference set up as MM stage with 47kohm input impedence/ YS Audio Solo MC step up transformer.
Acoustic Zen Silver ref cables.
Conrad Johnson Prem 17 pre
Pass Labs Aleph 3 power
Living Voice Avatar speakers
As I said above, I really enjoy the vinyl reproduction I get, but at times pick up radio stations at a clearly audible volume. The problem is worse in the evening, I seem to remember an explanation some years ago, why radio station interference is worse in the evening, but can't remember what it was.
I've tried dressing cables, Bhuddist mantras, meditation, nothing works. One thought is the phono stage sits under my turntable on a Mana Reference wall stand, the iron frame of which might encourage radio pick up, but I've nowhere else I can easily put it. I asked the UK Clearaudio importer a helpful guy, who sucked his teeth and suggested trying Shakti On Lines, or the Shakti EMI interference block.
Any thoughts on whether this or other ideas might work? Anyone else had a similar problem? Advise would be very welcome

You find ferrite where you find all things high end, Radio Shack. |
I've responded to interference questions before and this is no different. I think I have a solution for you: I live less than one mile from a strong AM tower. I could hear the station through my system. I replaced my interconnects and speaker cables with Canare cable and the interference was gone. I didn't have to move anything. Canare is inexpensive and is used in pro sound applications and by a majority of the recording industry. |
May I add a question for the solution of a similiar problem. I run a Scheu Premier (Eurolab) TT in to a McIntosh C200 preamp. I use both an Ortofon Venice MC and a Cartridge Man Music Maker III into the MM-input of the Mac. Woth the Ortofon, no problem. With The Music Maker, an audible hum and sometimes radio reception. I guess that by shielding the cable, I could get rid of the radio reception, but not of the hum. Are there other methods I do not think of. The Scheu-Tacco-arm I use has a Scheu-developed silver wiring which goes all the way to the preamp, being connected with Eichmann Bullet Plugs. The wire itself is to thin to add another wire for earthing it to the Mac. Any suggestions? |
