You guys are making a much bigger deal out of using a universal chassis than it is.
All you do is find an older 19" tv, take the back off, and discharge it, then pull the neckboard off. Count the number of pins. There's only 2 flavors - 8 pin (small) and 10 pin (big- like g07's and 4900s used).
Next, find the 4 wires that run from the chassis to the yoke (not yolk like an egg, yoke, like you put around a horses neck for him to pull a plow). There's some variation of the colors, but they are two seperate windings. Unplug these wires from the tv chassis. Take an ohmmeter and measure both sets. If you get infinite or open resistance, you've got one wire from each set.
Write these numbers down. If you have an arcade monitor you can repeat the process on it - if the numbers match, unscrew the tube from your tv, and swap it into your arcade monitor. No yoke swapping required. If it doesn't match, then call alva or 8liners and tell them what you need. They'll want to know the tube size, number of pins on the neck, and the impedance of the yoke (the 2 numbers you wrote down earlier).
They'll send you a replacement chassis.
Once you get your replacement chassis, remove the old tube and chassis and bolt your tv tube into your old monitor's frame, and screw the new chassis to the frame. Connect up the yoke, and the new deguass strap and adapt the power supply and video wiring to your cabinet, and attatch the HV lead and your done.
If you don't have a frame from an old monitor, Bob Roberts does - i think he gets 15 bucks a piece for them. Goodwill has 19" tv's all day long for 20 bucks, and the chassis runs what? 75 or 80? So you end up with a no burn tube, and a new chassis for 125.00 or so.
I've got 2 or 3 of them that i've built up like that, and i love them, the picture is fanstastic - as good as any rebuilt monitor i've seen, if not better. Plus, if you look around a bit, you can get a nice dark tube, and they really pop colorwise.
Shavenyak - if you need help sometime let me know, i'll help you put one together. Its really pretty easy.
