After a test drive and setting everything up, I had a huge fight with the wife. Apparently this projector doesn't have the WAF, Ill have to either sell it as is or part it out.
The wife wants something smaller unfortunately.
Alas nothing wasted, I learned valuable things! 
Guess I'll have to go *shrugs* digital

fight aside, im still keeping it. its far too much fun to throw out.
i finally managed to get the focus right, it looks quite stunning.
problem is now that the top half flickers at the speed that the refresh rate appears to be set at, when i set the contrast above 50%, is this the HVPS acting up or is it the vetical deflection board? if i set the refresh to around 100hz the flicker is gone (but that is probably because my eyes cannot notice it anymore due to the speed of the flicker), i dont want to run it at 100hz because that stresses the tubes and the vertical board too much. also my projector goes CLICK sometimes and then the geometry changes, then it goes CLICK again and it changes back to where it was, the CLICK problem started yesterday.

100Hz doesn't stress the tubes nor the V board, who told you that?

I assumed that, as the projector makes buzzing noises as I go that High. If it's not the vert board but the hvps, is that fixable? And at what cost?

There is a temperature sensor on the registration amplifier heat sink. Most likely, that is what you are hearing. Try a 55 code and see if that is what the image looks like after a click. When the sensor gets too hot it causes the power to the amps to be removed. You might be using too much correction or there is not enough cooling air passing through the heat sink.
Try adjusting the Horizontal Phase for any effect on the flicker at the top.
The buzzing might be a cap on the Horizontal Output board. Adjust the Static Horizontal Keystone to see if the buzzing changes. If so it isn't a problem, just annoying.

This might be incorrect, but my Ampro makes a pretty audible click whenever the tubes turn on or off.
It also looses convergence sometimes but that was when I had the physical convergence off by a ton and I was relying on the electronic convergence to correct at extreme values (max in one direction, min in the other etc) trial and error but once I got it converged properly I only ever have to adjust the blue from time to time when I see it start to trail. The green and red rarely if ever go out of sync unless I accidentally kick the unit (it's on the ground)
sorry if that's completely useless info by the way, but I had many of the same problems you're running into with flicker and focus and all of it resolved when I finally converged the thing correctly.
