Bad RFI from turntable - using ferrite beads to fix?

[cvanc]

Anyone ever done it? If so please share details. It seems to be cellular getting in.

My Threshold FET 10-Pe (1994) phono preamp has ferrite beads on both inputs, hot and ground wires. I've followed that build technique on the 6 phono preamps I've built. I also use ferrite beads on torroid mains.

Hi cvanc,

Can you post details, like the cable lengths, if they are shielded or not, and the phono amplifier’s input capacitance, etc? I guess I’m wondering how you determined it was cellular and not another source?

Anyway, these might help diagnose the cause.
