Ordinarily*, pulling tubes might allow B+ to go too high, stressing the filter caps. But in this case, there's already a huge draw on the B supply. And you have a variac to keep it under control.

Just so that I have this right, I'm gonna next pull the damper, power it up, then start powering up the chassis, each time yanking a tube and watching the meter, looking for a change in voltage?
Basically yes, using your variac to bring it up each time. Actually, just do the damper> AF out> vert.out for now.

*One big no no would be pulling the H.osc tube while the H.out tube is still in place.
