Turntable hissing


I have a VPI classic that hisses (or buzz) when I play it.  I am using a McIntosh 7200; the ground is properly connected both to the turntable and amp, and not sure what else to do.  Any thoughts or experience remedying this issue?

thanks for asking. I am not sure. I posted it for a friend. will report when I hear from him 

Hiss is likely RFI, not a grouding problem per se.  Viridian's idea to short the unused inputs is worth a try.  But what the OP described as a hiss is later referred to by others as a buzz.

Yes as viridian said… isolate the source of the buzz. My VPI Classic 3 sig developed a buzz in the motor which disappeared with lubrication.
