BTW.
This is a strange exception..normally with the CRT board disconnected,
you should not get the orange glow you described.
I found it interesting. Although all other descriptions pointed
to "classic" CRT problem.

Hi Jeff,
A CRT which lost it's vacuum was the cause of R216 burning and the
arcing in the CRT neck. Installed a used CRT and all is well.
Thanks anyway
