Two Turntables and Hum Problems - Help Please


Hello.

I've got two vintage turntables and both are giving me fits with hum.

I have two separate audio systems. One turntable goes to my pre-amp and the other to my receiver. Each system has its own separate sub-woofer.

My pre-amp and my receiver are about 30 feet or so from the turntables. That's as close as I can get them. Obviously each ground wire is much shorter than 30 feet. What type of ground wire can (and should) I use to replace what I have now that is not working? Copper stranded? Copper solid wire? Silver-colored wire? Should the ground wire be coated in plastic or rubber or should it be raw?

I've seen some references to sub-woofers generating hum from turntables through ones' pre-amps or receivers. Any thoughts?

Thanks!

I would also make sure that your interconnects are shielded from the TT to phono pre.
18-20 feet is still mighty mighty long for a cable transmitting such a miniscule signal. Above all other cables I would try to keep the phono cable as short as possible (and make sure it was shielded). Without shorter phono cables (or maybe balanced cables) I would be surprised if you are able to get the hum out of the vinyl setup.
