After replacing my quadrupler and other cards on the path to a working projector again, I find myself going through the entire setup procedure. It has been a number of years since I messed with it. Anyway, one thing that has always bothered me is the inability to move the Blue and Red guns vertically during the manual alignment step. There doesn't seem to be a way to do this! I can easily move the tubes left and right to match the crosshairs. But I find both those tubes are too low compared the the green tube. Consequently, I have to do the alignment and convergence digitally and find mysef pushing the limits of the projector. For example, I now have the blue gun converged vertically, but the digital range is all the way to zero in order to accomplish that. I know this is not good.

Any ideas on how to get the 3 tubes aligned better in the vertical direction?

Thanks, Chris

On the sync/vertical deflection board there are adjustments for : vertical rastershift blue/red and vertical amplitude (height) blue/red. Those should do it.

Thanks! The vertical rastershift adjustment did the trick. Everything is closer to midline on my digital convergence now.
