Meh, in any case, if you get the dreaded trace deflected off the CRT and you can't get it back with the controls, the input dual FET might be bad. If it is, apparently 2x 2N3819 TO-92s glued together face to face do the trick, as long as you swap over the pins properly.
Balance is a bit off, but at least it displays properly again.
Maybe there are better FETs with a better pinout, I just shopped for parts in stock locally.
