Ground net
 
Hi!

I need suggestions for a zero result.
I have read of putting the ground of the circuit to the ground of the earth via RC with R = 470KOhm and C = 1mF.

At the listening test the result is very little.
I have thinked that 470KOhm can be exagerate, and maybe 1mF also.

In your experience, what do you suggest?

Thanks,
Bye!

try to give us more information

even if using Google translate , you need enough words to express your self - what , where , how

are you speaking of toaster , or TV , or dvd player ?

You are right. I have a passive pre amplifier. Normally the ground is unplugged. Now I have read that is better to connect the ground to the electrical system of the house.
Better again, is to insert in serie to this ground a net filter with RC in parallel.

I hope to be understandable now.
Thanks!
