I recognized a CRT tube at the local surplus place (R@RE NEW IN BOX! :-)
that looked like the CRT from a VT320 and I bought it ($2.14 including
tax), took it home and opened up my worst VT320 (this is one I had already
tweaked the internal "brightness control" so that I had enough raster to
see it) and sure enough, same Phillips part number. So I carefully
disassembled the VT320, removed the old tube, put in the replacement tube,
and voila` a nice bright VT320 with no screen burn at all. Alas it was yet
another amber tube, I really wish I could find some green tubes which I prefer.
Anyway, yet another piece of classic equipment, brought back into peak
operating efficiency.
