yeah, beside what Tapedeck told you I would try to troubleshoot from here connecting the gear 1 by 1 and checking when it appears. I had this @@@@ with FinalScratch interface, which was powered from outlet + whole turtable setup and a laptop cable with two prongs (originally). This noise only gone away when I unplug the lappy from outlet, or if I connected it to the same outlet where turntable setup was connected.
