Usually the biggest problem today is age-related problems like bad capacitors, bad wiring, etc. and tube related problems are fewer as the sets have been idle many years and have not been using the tubes.
TV sets seem to be often designed right to the edge of tube capabilities and when the sets are run for 10 or 12 hours at a time every day, some tube failures seem to happen after about a year or so of this kind of use.

I'm not sure. I think its probably dependent on a lot of factors. My experience is that its always a bad cap, almost never the tube. In fact bad caps blow tubes. Rarely the other way around.
I've got a little Portacolor on my desk at work that I bought from Adam over a year ago. Its sat there running everyday for 14-16 hours a day and still operates the same as when I got it. I use it to monitor the station I work for. But, other than snickering from some fellow employees I have had no problems with it. So I guess millage will vary.
