How to make a degauss coil for servicing out of a junk BPC TV

[dtvmcdonald]

I have another way of making a degaussing (deTeslaing?) device.

Find a big (emphasis big) old power transformer, preferably filament but any will do.
It only has to have a good primary. Several pounds is best but any will do.

It has to be made with E-I cores. Take it apart and simply remove the I part of the core.

Carefully tape up any unused windings, attach a cord to the primary, and plug it in.

Up close this will demagnetize lots of things that CRT degaussers won't,
and its field equal a CRT degausser far enough away to degauss CRTs.
It will bulk erase VCR tapes. It will seriously damage 2" quad videotapes.

Same distance on-off advice applies.
