Eliminate the buzz ? ??

I currently have a Classe Cap151, Project Xpression turntable, a Music Hall PA 1.2 phonostage, & Vandersteen 1c loud speakers. THere's a buzz only out of the input the turntable is hooked up to. I know I need to ground the turntable, but the amp doesnt having anywhere to ground it to. Just need some step by step trouble shooting to get rid of the buzz, without spending much or anymore money. Thanks John. Should this be posted elsewhere?
