But I am having a nightmare time with static and popping etc on the turntable and someone said I have not grounded the turntable.
Try it a few ways, sounds like you cannot make it worse.
If you bring it over to the RCAs/XLRs you could tie it there if there is a place… or run it around/with the RCAs and tie it to the preamp.
Just make sure. It is slack enough that it is not like tying the house outside of a saloon and keeping the sub platter from moving.
