If you have confirmed the vert output stage transformers are ok, simply
by checking the resistance across the windings that are printed
in the schematic, then it's possible the osc is just not running....
Don't forget the vert. yoke winding too...

The timing cap and resistors with the red dots are pretty critical,
you should be sure these parts are in good shape. New or
at least checked, and you know they are good... and correct values.

Do you have plate and screen voltages on the vert output tube...?
Around 300V ???

Also the vert lin. control pot, and that r111 I think it is that goes to
ground after the pot, please check it too....
