Looking good. Do those jail bars move sideways when you adjust the horizontal hold? You could try adjusting the horizontal drive and see if that has any influence. The diagonal lines are just vertical retrace which is pretty common on that period set. There's a possibly you can add a vertical blanking circuit once you get all the other bugs out. Make any headway on voltage measurements, and locate the b+ going to the tuner?
