Copper foil


I just recently started a DIY project and wanted to know if anyone knows of a copper foil distributor or manufacturer. I am looking for .0075 thickness which is hard to find. Also, if you have info using the copper foil I am curious how you are using it in your system.

Thanks

I am using very short (18") copper foil for my speakers. The performance is simply astounding. Rewards including, surprising depth, detail, separation, and extension extremes are beyond expectation.

I gave my ribbons baggy insulation by wrapping the ribbon with Saran Wrap. It has been proven to me dielectrics are the signal's worst enemy.

My ribbon is .003" and 12 gauge. I just unwind what I need from a ribbon inductor.
