Mysterious shiny new deflection board in WG6100

Hi everyone,

I just bought a nice Tempest machine with a non-functioning WG6100
monitor. It looks like the HV board caught on fire. I have found
rebuild guides and schematics online, so I am in the process of
attempting to rebuild that board.

However the main reason I am posting is that I was shocked when I saw
the deflection board in this monitor. It is shiny and brand new
looking, and totally different from what I am used to. I have been
out of the vector game collecting loop for several years and am just
now getting back to it with this Tempest project, but I used to own a
few Atari machines with WG 6100s and none of them had anything like
this. Could anyone tell me what this board is and where it comes
from? Here is a photo:

The other problem with my monitor is it has a HUGE burn spot in the
center. I've been googling and looking at old forums threads, and
from everything I've found it sounds like the CRT tube situation is
really dire. I was wondering if there were any sources left at all
for replacement tubes (used or new), or if they really are completely
gone now. I've read that some TV's in the 80's used the same tube,
and I had the idea of trying to find one... but without knowing which
ones use the 19VLUP22 it would probably be an expensive failure.

Thank you for any assistance,
Xyla
