A pot is a potentiometer. It's what you turn when you want to turn up the volume on your radio. (unless you have one of those new-fangled kind where you push a button to make it louder) The one that is broken on this board is the horizontal size pot. I think it's a 100k potentiometer, easy to replace. Unfortunately Radio Shack doesn't carry them in the right size and that's all my options in this neck of the woods. Fixing it this way would cost about $20 (assuming you need to buy a soldering iron as well as the part).
As far as "8-liners," that is a guy who builds monitor chassis to turn any kind of working tube, from tv or broken arcade monitor, into an arcade monitor. He's pretty reliable; most people say his products are great. Check his site out at
www.8liners.com, or, more specifically,
http://www.8liners.com/datatech/monitor.htmlThe model number is Nanao MS8-26U. It came from an Indy 500 cab. It's CGA/EGA switchable. (low/medium resolution) It's also the same model found in most Virtua Fighter cabinets. Using an 8liners chassis would cost about $100 for the repair...not so much a repair as a refurbishment, really.
Either way, it's pretty cheap and it's a decent monitor with very nearly unnoticable burn-in. Let me know as soon as you can, I'm leaving tomorrow (Thursday) around 10 am. I can send pictures this evening if you need.
