[Sorry 'bout the late reply; I'm just catching up on posts after having been away from the forum for a bit...]
While I can't find or remember the book I saw this in, a few months ago I was flipping through an old TV repair book and it described a simple method for constructing your own color CRT degaussing coil. Unless I'm hallucinating, the instructions were basically:
- Get some ordinary 18 gauge insulated wire (single conductor, type and gauge not critical)
- Coil it up into a ring about 12 inches in diameter (I don't remember the number of turns you were supposed to make, probably something like 20 or so)
- Wrap electrical tape tightly around the loop of wire you just made to keep the coil turns held tightly together
- Strip both ends of the wire and connect them directly to an AC line cord.
...and that's it!
At first, this idea seemed a bit too simple (and perhaps unsafe) -- would a simple coil like that generate enough inductive resistance to prevent it from looking like a short circuit? ...but come to think of it, that's probably pretty much how a commercially-produced degaussing coil is made anyway. Any thoughts? Am I forgetting something important here? Would this be a practical servicing tool or a death trap? [...Then again, I think this might have been something I saw in a TAB book...
