Wow! Excellent job Mattis <thumb up>
I have seen that HP2640 when it still was in bad shape. The HP2640,
that I have, has many tiny spots on the screen. Your ?result after?
really looks fantastic.
Thanks Henk! I have a few more screens that need fixing. The most difficult
will be the Tek 4016. So I need to do some practice before that one.
What?s not clear to me, after removing the old
?protection? sheet, did
you apply some new ?protection? sheet, or leave the tube ?as-is? ?
I doubt whether that ?protection? sheet would really help much if
the tube would implode (for whatever miraculous reason) ?
No, I didn't add anything between the crt and the glass. If it actually is
a protective shield then of course there is not at all the same protection
afterwards. But as Christian Corti mentioned it might just be an etched
glass to remove reflections. I know at the RICM when doing the same thing
on a DEC VR14 they added a sheet of lexan between the crt and the glass. I
think Michael Thompson can tell more about this.
