David, It would seem to me that while you have a warranty it would be prudent to exercise such a warranty. Otherwise, you will be fooling around till the last minute and be out of luck.
If it sat "off" for three years and you have only had it operating for a short while, unless I misunderstand something, it seems that there may have been a problem with tube from the start ? Out of curiousity, perhaps Corby can enlighten us on that aspect ?
