Have you either tested the vertical output and oscillator tubes or substituted them with "known good" tubes. Sometimes the substitution method is the best; that way there is no question about the electronic integrity of the vacuum tube.
There are so many possibilities that I guess people will hit on with this common symptom of no vertical sweep. I think that the next most important question to ask you would be: Was there vertical sweep before the "recap?" You could have a bad vertical output transformer, a potentiometer or a bad yoke. There are resistors across the yoke windings that can bad or have cold solder joints.
I'll stop there so some others can maybe elaborate. I hope this helps.
