NICE!

There are probably a few bad capacitors in the vertical output section - if not a driver/output transistor as well. Also look for open or increased resistor values in the vertical output circuit. Any one of these can cause the foldover you see.

all that use and abuse after yeArs of use kill caps in those video monitors. I worked on a few of those in the past for an arcade center up here and slot of them were always leaky elecrolytics and resistors. Good luck that looks like a sweet and clean arcade!!
