The built in Focus and G2 was one of the reason's I thought using a
new fly back would be cool. I imagine finding the separate Focus/G2
assembly might also be a pain...

Clay's idea of using a GO-7 fly back is nice though, since we have all
its spec's (well, at least a schematic of a working monitor). We
would have to come up with the focus assembly though (Or would we? I
don't have a GO-7 monitor, so I'm just assuming here...)

I just saw a thingy called "Transformer Horizontal Drive" on the Happs
Control page
http://www.happcontrols.com/amusement/monitors/49125000.htm
which is most likely one of those things I've been calling a "Current
Boost" transformer (because of what it does), and it's only $3.62.

Another alternative to the current boost transformer would be to
simply use more transistors to increase the current without the use of
the transformer. This should work unless the transformer is also used
to "round" the square wave a bit before being given to the final drive
transistor, or if the reverse voltage that would come from the
transformer is used to more quickly turn off the output drive
transistor, or something else I can't think of. Probably ought to
stay with the tried and true driver that seems to be used by every TV
made, and keep the transformer.
