I just put an Amplifone in my Tempest ( more on that to come later in a separate post) and came up against the problem of a HV board missing the focus/screen adjustment assembly. I took one from a junk G07 chassis and mounted it to the existing metal bracket that is riveted on the HV board. I had to drill 2 new holes and shift the assembly a little more towards the heat sink and away from the flyback so it would fit. So far it works great. It almost seems to be easier to focus as if the range is better. It comes in and out of focus slower so you can dial it in easier ( although that could just be me imagining it). Just wanted to throw this out there in case anyone else has the same problem although I think it's rare that these boards are missing that assembly.
