[TV] Re: Removing the Coating on the back of a picture tube possible?

["Star-Tech" <STAR-TECH@xxxxxxxxxxxx>]

Hello Dave:

                 I would not recommend doing this because
the shell of the CRT has a ground line to it, however you
might try to sand a small section about 2 or 3 inch's in a section that is
not near the ground strap. I don't think you
will be-able to see the mask because of the high volume of light.

                                                         Greg Zumbro
