Marginal tubes can cause issues like lack of oscillation, but usually there should be some deflection especially if you had deflection before the recap.
Recheck your work in the vertical circuit and make sure you didn't install any end of any vertical stage cap to the wrong terminal in the set. Also check B+ voltages to the vertical. If you lost a power supply rail that feeds the vertical that could cause no deflection too.
One thing you can do as a troubleshooting measure on a transformer powered set like that is connect the grid of the output tube to the heater line with a .1uF cap and see if you get some deflection.
