Electrostatic Shields


2002-04-20 4:44 pm
Does anyone know where it is possible to purchase electro-static shields for transformers (not toroids as this is a tube project.) ?

The transformers which I am aquiring for my current project have either bell ends or are bare. As I am mounting them on the top of the chassis, I would like to have them covered up. Non-inductive metal (ie copper, aluminium or brass) would be my number one preference. I have been scouring the net for parts dealers which sell shields sepearately from their transformers and have found no joy.

Thanks in advance.:(

You could solder up a brass or copper box, then sand/file/gind the corners and paint it.. dont know if you're into that though..

A Power tranny i pulled out a 50's TV the other day seems to have one tap with continuity to nothing, and it was grounded. I assume it is some kind of sheild. (big honking pT too :))
