Hey, i really need some help here. I have a pioneer turntable running through a preamp and then into a play 5. The problem is that suddenly the sound becomes badly distorted to a point I cant hear anything. What's weird is that after a few days of me trying things it starts working again. It will play fine for a bit then the same thing happens. I've bought a new preamp as I thought it was that, the turntable has been serviced and rca cables are new.

Any ideas anyone?
