This is an excellent article and one we should have a lot more of in
this group. Some of us out here are trying to keep vast amounts of
computer equipment on the road with little or no help from the
manufacturers.

If anyone has any details for the SONY monitors used on SUNs and HPs
I'd be delighted to see them.

I actually knocked the neck off the tube on my Bosses MAC SE :-(,
fortunately it turned out that the tube from a temporarily available
Mac+ fitted and bailed me out of that situation, however to get the
tube repaired cost me #23 sterling inc. tax at a local regun shop - so
don't despair if you have cracked the tube, as long as the phosphor is
still OK, you'll probably be able to get it fixed.

This goes for old and defocussed tubes from all monitors VDUs etc. We
have had some success in having elderly terminals regunned, but bear
in mind that there is nothing that can be done for screen burns.
