The way we reglued the yokes was clean up the bell
so the glue will take, get the picture perfect & wedge the
yoke. After triple checking for perfection mark tube &
yoke with marker & check again. If OK pull chassis put
on face & reglue. We used 2 part epoxy. You can get
at the dial light now.
The hoz hold may be just a dirty control or maybe an
electrolytic on the hoz osc board.
The vert board was the only other problem. The socket
would crack & vert go intermitant. If they kept running
it the socket & board would cook up.
For date check for date codes on CRT etc. It is 74' ish.
