OT: CRT EMI Shield

Many times such a course of action will magnetize the shadow mask and other parts of the CRT beyond the ability of the internal degaussing coils to correct. But O well..... To the original poster: As for stacking tubes one on top of the other - if it's just the one that's causing the magnetic pollution, I'd be inclined to chuck it (at your appropriate nearby E-Cycling facility of course!) and just get another. They're common as dirt and as folks trade up to LCD screens, CRT monitors are hitting the recycle streams in epidemic quantities. Nobody wants a 100-pound 23" CRT that takes up half the desk anymore... If you must shield them, then use reasonably thick (1/8" to maybe 3/16") *iron* sheets if you can it - magnetic steel if you can't. And Home Depot. Lowe's, etc are going to stick it to you if you buy such materials there... it's unbelievably outrageous what the charge for bar stock, angles, and sheets.... any little funk metal shop or machine shop will have tons of this stuff lying around for cheap... Just my 200 millidollar. John
