Driving a round tube with a rectangular chassis?

[RetroHacker]

Well, I finally managed to find a round picture tube. I believe it's an FJ - it has a bonded safety glass. It still even has the yoke and the base connector attached - it looks like someone chopped up a console and just hacked all the wiring. Unfortunately, I did not find a chassis with the tube. I actually do have a cabinet though - a while back I found a GE roundie cabinet, but no innerworkings at all. So, I have a cabinet and a tube, now all I need is something to drive the tube. Has anyone had any luck driving a roundie tube with a rectangular chassis? Seems like I remember someone saying something like that a while back. I don't have a suitable chassis at the moment, but I might be able to find something, especially if it would be possible for me to use a solid state chassis. Too bad I can't use one from a modern inline gun set - those are much easier to find!
