Rega P25. Getting radio signals thru interconnects

I have a stock Rega P25.
Seems to be picking up radio thru the interconnects.
Any suggestions?
G'day, if ferrite clamp on chokes don't work, improved earthing (grounding) is normally the answer.

These sorts of issues can be bedevilling but usually can be solved through proper investigation.

Try connecting the TT earth wire to different chassis points. That may give a clue. Regards, Fap.
