And please don't forget to rate me positive when we are finished. Let's get you fixed up so you can be on your way. Touch the turntable and the amp at the same time. Does the buzz go away when you touch both? Be sure you are touching a screw, and not a plastic housing.

Hello Rusty, I tried as you suggested but the sound is still really distorted.

Expert:  Rusty replied 2 years ago.
Ok, some turntables have a built in preamp. That boosts the signal, the same as your phono input on your amp, resulting in over-driven signal which causes distortion. Connect your turntable to the aux input, or any other available input other than Phono, and the signal levels will match. Tell me how it sounds.

Thanks Rusty you are a star. One thing. Will I get an inferior sound quality. As I'm in the aux input?
Expert:  Rusty replied 2 years ago.
Absolutely not. Your turntable has a built in preamp. Your phono input is a circuit with a preamp. If your turntable didn't have a preamp, you would use the phono input, and it would have the same quality, if not less than you will achieve with your turntable into the aux input. Aux is the correct place for your turntable.
