VGA to JAMMA video amplifier - diagrams / infos?

some of you may know you can get VGA to jamma if you have the right resolution set, by soldering the RGB and syncs to a jamma connector, but the image contrast and colour depth is feint due to VGA coming out at 1v, instead of the 5v (I think) that jamma needs to display right.

I know ultimarc produce a small and cheap-ish one, but I might need a large amount of these, does anyone have a small circuit diagram of something small, and cheap to produce that would do the job?

The Direct Coupled Video Amplifier sounds like what you're after.
