At first there was no sound and buzzing, but after realigning the sound IF and detector transformer, the sound comes in good.
The sound IF was so far out of alignment (it was turned all the way one way) that I think someone got in there and messed with it, not knowing what they were doing. I think they probably did the same with every other adjustment, this is why I'm so certain my problem is alignment. Remember this was the set in which someone had also installed the wrong yoke and fly from another set.
I put some pics over on the arf a while ago, both with the 8XP4 test crt, and the set's own 16GP4. Retrace lines are a problem, but otherwise the picture's fine as long as there's no sound in the signal it's receiving. Completely 100% recapped all paper caps and electrolytics. I understand there's some micas in the horiz oscillator which also tend to go bad, but horiz sync is good, so they must be ok for now.
