Thanks!
I already made sure its not the CRT board, I've swapped that out and the issue persisted. The same board works fine on a different CRT (See my above post, I use the same CRT Board)
The only thing I've not tried replacing is the yoke, everything else has been swapped at some point.
Basically a different CRT with same internals does not show this issue (Same PCB Board too). Its only on this specific tube (and maybe the yoke, as that is the only "somewhat" removable part I haven't changed)
