On the point of having a well regulated supply for the screen, I've considered making something like this to be a super stiff screen supply. I know that there are some people who would find the use of solid state things to be bad, but I'm open to all possibilities.By changing around R2 and R1 in this, you could make the screen voltage whatever you wanted, and it would be pretty much independent of the currents involved (so long as they weren't TOO high). Also, you could not use a BJT there, you could use a FET, though you might have to use a 10V zener depending on how much Vt+Vdsat+(regulator headroom) you needed. Just a thought.
