C2 did blow up - which is the reason why I replaced ALL capacitors at the same time, I probably should have replaced JUST C2 first and done testing.

I assume when I touch pins 3-through-6 of V10 it will cause the output plate of V10 to cause vertical deflection?

Why does the schematic say "DO NOT MEASURE" the plate output / Pin# 9 of V10? - The voltage doesn't seem THAT high?
The DC voltage yes, will not that high. But, with deflection working, the retrace pulse/period produces a high amplitude spike in the primary, sometimes near 1.6kV. This for every frame, aka. 60 times per second of these pulses (for vertical stage; 50 times for a lot of another countries).
