Aha! Figgered it out. The pot must indeed crapped out back in the day. There was a replacement pot installed where the optional UHF tuner would have been if mine had it. It looked factory to my uninformed eye, as the holder was indeed factory.
So, it does affect the vertical linearity. However, as I get close to getting the test pattern round, it starts getting egg shaped. So how it was is about as good a compromise as it gets.
One thing tough about working on your first set: I don't know how good was OK back then, picture quality and sound. So no way of knowing if it is as good as it gets or could be improved.
In other news, I bought another Predicta holiday (blond) and a parts set (holiday mahagony). I swear, I'm not a collector! :-) With luck I should have all the parts I need to keep a set running for a long time.
