Well I fooled around with the CRT some more tonight.
Seems it has a bad connection, or a short, either inside the neck or hopefully, at the socket.
I put it in my Conrac Monitor chassis to give it some more HV, it behaved the same as it did in a 10" chassis, Raster, no brightness control and no video information.
Tapping the neck caused it to quit altogether, very dim raster.
Soldered the pins and still no picture.
Put it on the Tester and started tapping, it suddenly went to the high end of good (pegged it actually) readjusted the G2 setting and checked again and it now tests like a new CRT!
How long this will last is anyones guess, till it cools of perhaps, is the problem inside or at the socket, I don't know at this point but darn it has a nice picture right now.
