CRT Phosphor maintenance

[bgadow]

Same as the others-I have never seen phosphor damage on a stored crt. Indeed, the only phosphor damage I've ever seen were on tubes that were abused-either run with the vertical circuit disabled (burning a line into the screen) or with the ion trap misadjusted (an issue only on early sets.) The cathode will need reenergizing after a very long period of sitting but just running it awhile will usually take care of that. I have seen CRT's that took what some would call abuse (decades in hot attics; years spent outside on the ground) and they still worked fine with no phosphor problems, both bw and color.
