We need more info on the vertical problem.
There are two different vertical schematics. One in Riders, one in Sams.
Which do you have?
What value HV caps are you using to connect to the deflection plates?
The Sam's circuit is better, and I recommend increasing the capacitance
from .005 uF to 0.02 uF. 3kV ceramic caps in parallel are OK for this,
though the ASC film caps are "officially" better. My set uses ceramics and
has great linearity.
