Connect that ground to where the house ground and lightning ground are connected thereby creating a star ground. This way the voltages across the ground rods will be the same in the event of a lightning strike. As a bonus, the (somewhat) equal voltages will deter stray currents into the neutral and lower that hum even more.
Acceptable Level Ground/Earth Noise
Hi Everyone
I have a dedicated earth for my audio system. I was digging a bore for water and lost the rod so decided to dedicate that bore for Earth. It is about 100 feet deep an is in water. The line runs straight to my dedicated audio room and is shared among the various audio components.
I am running a Clearaudio DC preformence through an Avid Phallus phone stage hooked up to a ML No. 38s pre. The cartridge is a clear audio virtuoso MM. The ML volume level goes to 92 and the hum appears at 60. Previously when the earth was shared the hum was almost unbearable at 60 but now is significantly reduced.
My question is that is the hum just part of the analogue experience or should it be absolutely quite?
