Turntable ground

I've had great successes in substantially reducing earth loop issues by using a wire from a stripped Telecoms Cable.

Using Wire of this type is extremely cheap, as an old redundant Ethernet Cable will be a satisfactory donor. Wrapping connections with a wire and creating a bridge between Input > Output has done the job to my satisfaction.

Typically, if a SUT is in the signal path. The SUT's - Input > Output and Phon' Input bridged with a cheap copper wire is a working solution on my ancillaries used to add gain to the generated and sent signal.

I've always wondered why there's no standard for ground in electonics. I think that would solve many problems for people.

Thx for responses. Was pleasantly surprised with this. As @billstevenson said accept that it works!

Good response. 

@skso1 - 4 cables? can you elaborate? where did you connect them?
