How Do I Build a Faraday Cage?

If you want it to work OPTIMALLY, you need to use thicker materials that are solid. The cage would also be attached to a low resistance Earth ground. Aluminum is FAR less desirable than steel and to a lesser extent, copper.

Using thinner materials that aren't solid i.e. metal screening, etc... that lack a low resistance path to Earth ground can also produce beneficial and highly usable results. How well you want it to work and how much you want to spend may dictate certain cost-cutting techniques to be implimented. Such are the design variables that any project / product encounters. Sean

PS... Don't forget to address cabling coming in and going out of the device as these can act as EMI / RFI conduits also.

Update for all:
The Faraday cage has been sidestepped.
I conquered the severe RFI by doing a number of things. The biggest impact was changing to a balanced junction box on my VPI TNT6-HR, allowing me to go XLR right from the tonearm output to the balanced phono stage input of my Atma-Sphere MP-3. The drop in RFI was immediate and undeniable.
Other steps that helped include placing ferrite rings on interconnects, moving the whole system away from the window facing the radio tower, shorting plugs in unused inputs(but never outputs!), moving to balanced cables from preamp to power amps.
Thanks to all for your advice. Hopefully, I won't ever need to build the Faraday cage. I had copper mesh all picked out and was ready to go. Glad I didn't do it. Cheers,

That's great news Spencer and i'm quite certain that this approach was FAR easier to impliment. Most everything that you've mentioned are known cures to known problems, so it's good to see that some of the old stand-by approaches still work as expected : )

Now get out of here and enjoy your system and all of the work that you've recently put into it : ) Sean
