Eric, those monitors (may be the same one also called the XBR Pro) cost about $1800 when they were new, in the 1988-1992 range. As you saw (or will see), they have an awesome picture if the CRT is good. Get a Channel Master CM-7000 digital TV tuner, which has an S-video output, for it.

I still have a couple of those that I picked up independently years ago while I also supported hundreds of them at San Francisco and other airports (including LAX) where they were very widely used as flight-information display monitors. After years of 24-hour use, often in enclosed cabinets with four to eight monitors each, the CRTs do go bad (losing one or more of their colors). There is a power module in the power supply that is no longer available (since we already had replaced it in most of those hundreds of monitors!), but that kind of failure only happened after years of 24-hour operation.

The matching tuner from Sony was model ST-7TV or similar.

Those monitors were near the pinnacle of NTSC displays, with the one limitation of having a "cold" picture (9300 color temperature) standard with no easy way to adjust it.

One failure that may happen is that the display may have a "barrel"-shaped look (pincushion distortion). That can be fixed with a few electrolytic capacitors; if your set has that problem, let me know and I will get you the list of needed parts.
