Man, I don't know what is going on, but in the last 10 months I have replaced 6 power tubes and 3 preamp tubes. Two of the preamp tubes only lasted 2 months. The power tubes only lasted about 6 months. One of the tubes that only lasted 2 months was an SPAX7 which is supposed to be Mesa's higher quality tube. All of the tubes died within the warranty period and got replaced for free, which is great, but I'm not feeling to confident with the quality of Mesa tubes now.
The amp is probably on about 1.5 hours a day (every day) on average. I think the Mesa tubes sound good, but I think it's time to try out some other brands and see if they last longer. Anyone else have tube longevity problems?
