Phono amp RFI problem

Hi everyone,

Just added the amazing LFD LE/SE phono stage to my system.  It sounds great, but it picks up local radio stations (clearly enough that I know there's a sale at the local boat shop!). I've tried moving the unit around, but it still picks up the signal.  I'm using a Silnote phono cable, and I've never had this problem with any other phono stage.  Any suggestions on how to deal with it?  

Thanks, Scott

Perhaps I should have provided further info on the system:  VPI Traveler with ground wire connected to the phono amp.  LFD Mistral integrated amp, JW Audio ICs from the phono amp to the Mistral.  JW Audio speaker cables to JM Reynaud Silver Bliss speakers.  Help!

Thanks, Scott

Hi Scott,

This thread and this one describe several approaches that you can try.

Thanks, Al. A short term solution I just figured out was to braid the phono cable - that seems to have stopped the radio station from getting through, and there’s only a slight bit of hum. Will read through the threads and experiment a bit tonight after work.
