On the FBT there is a fiber board with focus & centering parts.
Part # is there, format is S-#####. Post that & I can look it up
& check for subs. It was a common one.
On these the focus sticks go bad & cook some resistors. Also be SURE the
the damper & HV reg tube are the right pair per layout chart.
IIRC the new OEM also comes with a new HV rect socket, a nice touch !
