Brilliant! You need to patent that.

My father did that around the late 50's to demagnetize screw
drivers.
I think every TV repairman knows that trick.

I inherited that from my grandfather.

I'm not surprised.

You and I and Michael are probably the only ones lurking here who
know
what a degaussing coil is (and how to make your own ;-)

...Jim Thompson
HA!! You and a million other technicians!


HA! yourself. They might know how to use one, but I've seen some
spectacular flames from homebrew coils made by half assed techs.

I made, and sold a bunch of them while I was in high school. A
decent commercial coil was $75. Mine had twice the turns and were made
with a heavier gauge double cotton, double enamaled wire that was
surplused by Picker Xray. They also had heavy duty momentary
pushbutton
switches and a 20 foot cord so you didn't need an extension cord. I
sold all, except the prototype in 1969. I still have the prototype.
You
could see the effects 20 feet from a color TV screen, when you pushed
the button.

Which probably isn't too good for the low power purity and static
convergence magnets on the tube neck!


Not of you didn't slide it over the neck of the CRT.

When your degausser has a 20' range you don't have to!
