[QUOTE="excollier, post: 993258, member: 284272"] Thanks for your thoughts on this. Where would that item go? Between the turntable and phono inputs? I spoke to the main distributor for Rega in Northern Ireland, the owner of Lyric Hi-Fi in Belfast. He is confused with this and we went through various ways of grounding the turntable that you would think might cure the problem but to no avail. 1.Tried connecting the outer part of the rca plug that carries the ground to the amp, directly to the earth connector on the amp - no good. 2.Connecting a wire from the tone arm to the amp's earth point - no good. 3.Earthing the amp's earth point to the mains earth pin on the power supply plug - no good. 4.Combination of 1 & 3 above - no good strangely if I pull out the left channel rca plug from the amp, the one that carries the earth connection, the noise gets louder, but if I then connect the earth wire from this disconnected rca to the amps earth point - no noise, gone!! Plug back in and noise is back. This is a real pain and points ever more towards a new amp :( [/QUOTE]
