I have managed to remove the outer screen on a couple of DEC VR201's that
had the blue spot rot. I sacrificed the outer screen and removed the soft
layer beneath. It's this layer that has the problem.
Breaking the glass sounds a bit drastic but there's no way to put it back.
The tube goes back in the case and you can re-site the rubber stand-offs to
maintain the gap that now exists around the face of the tube.

A thin flexible metal ruler and lots of time (2-3 hrs).

Hi
I'm told a thin piece of music wire or guitar string
is what to use.
Most just leave the shield off. I'm not sure if one
could replace is without some heavy duty vacuum
equipment.
