Do check if it does have dynamic focusing as many of the big ones did. We can hope!
No idea, previous owner likely never even noticed. It's my curse I suppose seeing these things.

I think AE2 chassis of this generation had a D1 board for that, this doesn't have one sadly. It is filthy inside so could possibly have a few caps that have leaked. I actually think it's spend some time in a shed or garage at some point, it does smell a bit rodent uriny, so a good clean at least I think is in order.

I do somewhat suspect the flyback isn't well either, turning it on from cold you can hear some pretty distinct arcing coming from that area, sort of like a fizzing sound accompanied by what I can only describe as "high voltage smell" if that makes any sense at all! It does settle down after a bit, the focus doesn't change in this transition though.
