I was looking at a sega blast city knock off cab today that looked to have had the original tube and chassis swapped. I should have taken better photos, and can do on Monday, but I didn't immediately recognise eithr the tube or chassis. It is a 29" tube and it had a yellow slicker with "fortune" in black lettering on the side. Chassis was pretty standard with s/video, component and RF but no rgb mod and a terrible picture coming in via RF. I initially thought that i would work it out monday, but i gave the guy a rough quote for an rgb mod or chassis swap and he has just decided that its not worth him picking it up. Now its driving me nuts trying to work out where it may have come from as I want to know what I got myself into here.
 
Ok it's a fortune 73sx731y22-dc01 with a generic chinese chassis. RGB mod is possible as the chassis is designed to take a SCART but just doesn't have one.

Opinions on the best course of action.
RGB mod the existing chassis. If I was to do this I would probably design a pcb to take a standard JAMMA 5 pin video plug, attenuate and buffer the video input for SCART and output via SCART so you could use a standard cable.

Replace with modded aliexpress chassis. If I was to do this I already have a 220-110 isolation transformer handy but would need to do caps, B+ resistor, and a few other bits and pieces on the chassis, plus buy the chassis and I have no idea of what neck pinout, inductance, heater voltage etc etc that that particular monitor runs.
