I think a lot of modern day tube preamps are hard on tubes. I have several that vary, CJ premier 14, et5, and Audio Research ph5 all eat tubes. Allnic h3000 and dehavilland ultra verve 3 tubes have lasted thousands of hours.

The old adage that signal tubes last 1,000 to 1,500 hours is complete bull for some preamps.
