Using the Motorola schematic and the power supply shows b+ 150v and b++ 300v however all that’s there is 276v and 111v so this low b+ could be the reason why the vertical and horizontal seems to be fighting each other at least that’s what it looks like on the screen. The first and second clipper has 2 pins looks like 2&6 that b+ feeds but it’s to low so hot to find out why and it looks like either something in the ballast or a defective power supply cap that feeds the b+.
