the u5000 was plauged with a mutitude of problems, due to bad design and/or faulty components. There are some repair/upgrade kits that you can order to fix the problems these monitors have with their power supply and the horizontal/vertical sweep. these monitors where replaced with the k7500.
the tubes are not great, they get dim to the point where no amount of adjustment can get a good picture. so if the tube is good, and if it's free or super cheap, it could be an okay monitor. be aware though the unit is a medium resolution display only (some where switchable to standard (maybe that was the k7500) the board will have a plug you can move.)
