I think I have some way to go (if I ever get there) before I get to the linearity of your screen shot. Since taking my previous screen shot I checked the value of the anode load of the line oscillator triode and found it to be 920k instead of 820k and got a slight improvement but it's still far from linear.

I also need to look at the frame linearity that currently defies adjustment despite a good range in the controls.
