It's got a really bad vertical fold, but I've already replaced all the electrolytics. The vertical tube was really weak, so it got replaced with an NOS one same thing with the audio out tube. Not that I care about audio at this point, but it is one of those chassis that forms a voltage divider through the 6AQ5 audio tube, so I figured why not take care of it. I don't know if the linearity pot has just gone bad or I'm not adjusting the right one, but no matter what I do right now I can't get it to look right. I'm tempted to blame the output transformer, but I don't have another I can sub in at the moment. There's also a ,001/2kv cap still on the PCB that's original, I suppose that could be bad. It looks like it feeds vertical pulses from the plate of the output back to the multivibrator, so it's probably semi critical. I'll have a look at the resistors and swap out that cap.
