Copper Sleeve over IEC


There has been several threads on AA about putting a 1 1/2" copper union (coupler) over the IEC on the CD Player, Preamp, Amp.

Well I tried it...

Anyone else give it a try?

Kenk168, in this case it really should not matter much in the gauge of metal used, its going to block the same for the most part, only reason I could see thicker being better would be with a really strong inductive/magnetic field, but I think this would be far more power than what we are able to run in the house. Essentially this might work even just using Aluminum duct tape, or copper tape wrapped around the connector a few times, problem is that a roll of that tape is probably a lot more expensive than a few of the 3 dollar plumbing pipes we are talking about here!

For example there are many hi end manufactures that wrap just the transformer in the component with a simple foil thickness type metal with good shielding results. The only other advantage to thicker being possibly better would be simply the mass adding more mechanical damping, but for the shield properties if thatÂ’s what your going for I really doubt you would find much of a difference.

Who knows maybe just balling up a strip of the aluminum foil in your kitchen right now might be just as effective! But it would not look as cool :-)
Kenk168, I think they are the same thickness, standard wall.
There is a standard wall, a X-hvy and a XX-heavy wall thickness.
Almost all domestic copper is standard wall.
The thicker walls are used for Industrial use.
The copper couplers are working extremely well in all locations.

My crappier recordings are sounding very listenable, and at loud levels.

This is the most effective, cheapest tweak ever applied to my rig, and I've done many over the years, installing my own IEC inlets, various fuses, damping of chassis, footers and materials etc, etc.
If you do a search for rfi and emi shielding materials you will find many different types and variations. The foil types made of copper with adhesive maybe the most simple to procure and to use. I have a couple of copper foil inductors I could unroll and use for this experiment/purpose. Some slicing and dicing along with some spray adhesive may open this up for some shielding inside of my cd transport. Tom
Tom,

I found a roll of 3 inch adhesive-back copper foil from McMaster Carr,
the inside of my CEC transport looks like a good place to start using it.
