[Coco] Degauss an old CM-8

I used to do that when I was a kid to fix TVs that got too close to speakers but always felt like I was doing damage. When I worked at Radio Shack, I used a bulk tape eraser.

You may get lucky and find a degaussing coil at an electronic parts place. I had 
such a coil with a Heathkit TV. It was a wire wound loop of about a 2ft 
diameter. They can be powered with a variac.
You don't want something that creates a small magnetic spot.

You are supposed to have the coil parallel to the picture tube, moving it around 
until the picture seems free of 'hot spots', move the coil away from the set, 
and finally turning it perpendicular to the screen. That prevents the degaussing 
coil from leaving its own magnetic impression on the tube.
Don't ever put a live degaussing coil near the magnets at the back end of the 
picture tube. :)
