RF filter from audiophool to realety.

FriedMule:
I am thinking about making a RF / EMI filter for my test bench.
I found this on a site for audiophiles and this is often a good reason, not to just trust it. :-)

Does this filter work?

Define 'work' :D  You should be able to plug things into it and get power out...

I don't like the look of the switched earth wire... I guess it is an attempt to stop ground loops.
llkiwi2006:
Putting an inductor in series with the earth connection is not a good idea.

Also, why not just buy an off the shelf ac line filter module? This way you don't have to worry about safety.
FriedMule:
My definition  of "work" is, do it as promised?
Minimize RF and deliver power.

Why I don't just bye, because it is a lot more fun to build. :-)

(by the way I know a lot more about main power, then I do about electronic. So I think that I am safe)
FriedMule:
I forget to ask if that circuit would be dangeros , if the plug with phase and null are switched around?
