I've resoldered pin 3 on the CRT base and socket. There is continuity between the socket and the PCB. The socket has been retensioned a bit. R366 is good.

With the auto trigger on the C of T353 is -867V no matter the position of the hor. ext button. The voltage only changes with the AT off.

I wonder if we are coming to the conclusion that there is a problem with the CRT?
