Monitor takes on a purple hue after about an hour of play. Monitor is in a KI2 cab. I dont know the type of monitor, but whats my moniotr issue/fix???

cap kit will not correct this, no.
what I would try first though is swapping drive transistors. if you look at the neckboard, there will be 3 transistors with heatsinks (usually) and they'll go in the order of the color adjustment pots on the top. actually, this is even easier, the affected one (maybe) will be the middle one. desolder it and one of the other two and switch them around, solder them back in.
permitting it's a transistor failure, you would be looking at a yellow tint if blue goes (assuming you chose blue as your donor and plugged the potentially bad green in the blue spot) and a cyan tint if red goes (same, just if you used the red transistor to swap)
if you've still got a purple tint, then it's not related to the drive transistors, but is instead a tube issue.
the way to correct that is with a monitor rejuvenator, which will clean the dirty CRT guns, and possibly give you a nice picture again. it does reduce the overall life of the tube, but what would you rather have a shitty looking tube for eternity or a nicer tube for a shorter amount of time?
cold solder on the drive transistors is also a possibility. you might fix the problem by just reflowing the solder on all the transistors.![]()
if you have a Hantarex Polo, those things are an absolute MOTHERFUCKER. the chassis will be an orange/brown color. it may even have a label on the neckboard that says HANTAREX POLO on it. or the power supply cage will say it too. I say they're a motherfucker because even if you discharge the tube, the transistors still hold a charge lol. I wonder if you can discharge those at the base without shorting them out..?
otherwise, I don't know what KI2's also shipped with... I don't think K7000, cause mine didn't come with an isolation transformer. U2000? I don't know.
take a picture of the chassis if you can get at it. I know that particular cab "gets in the way"
