Bob;
Disk caps on the CRT socket I presume. I think I have narrowed it down
to something shorted in the CRT socket.

Yes Ed,
It was the spark gap that goes around all the pin sockets.. it
was hitting one of the pin sockets.. Check all the disk caps to..

Bob;
I have about 150 volts on the screen Out..but as soon a I connect the
screen lead to the CRT socket, drops to zero.
This is even with the CRT board pulled from the tube.
Do you remember what was shorted on the CRT socket.
That screen voltage coming out of the Flyback seems low at 150, but I
suspect something shorted on the CRT Board.

Ed,
Don't have print, but did you check CRT and CRT socket for shorts?
Had a
set, the socket was shorted and took out the controls section on fly...
