No, try connecting the amp's ground screw to an earth first before
attaching anything to the turntable. An audio system should have one
earthed component, unless you have balanced interconnects.

You hit the target man, thanks a lot. I put a wire from the ground
screw of the Amp to another screw on the back of my CPU computer and
the buzzzz stopped, now it's a very small hiss but infintely better.

Thanks man.
