Need help with turntable (1 Viewer)

[CalvinC]

I have a Marantz 7300OSE that I am trying to connect my turntable to. The receiver does not have a phono input so I bought a phono preamp. The problem I am having is with the grounding. I connected a ground wire between the turntable and the receiver but Iam still getting a hum. In connecting to the receiver I have tried a screw on the back panel and the am ground with no luck. Any suggestions? Thanks!

What kind of pre-amp are you using? Might it be the source of the hum?

I've encountered this with cheaper (

It is a cheapie, bought off ebay for $25.

My NAD phono pre-amp requires the TT ground to go to it, not the receiver.

Do you get the hum if you don't connect the ground wire to anything?

It is still there but not as bad.
