2. Check / resolder all the connections in the vertical circuit.
3. Clean the tube socket for the vertical tube(s).
4. Check the caps in the vertical sync circuit.

I'm wondering about the vertical hold pot on it. It decided to be good today, ran all day without any problems. Do those pots have to be replaced or will contact cleaner do the trick?
