And another thing, if the amp is still under warranty and you change tube manufacturers and something happens to the amp, the warranty is voided. I love my Mesa amp, but that just annoys me to no end. It's cheap and low as far as I'm concerned. Is there another amp manufacturer out there that employs that kind of warranty policy? Not that I am aware of.
Isn't using non-Mesa tubes going against what the amp was technically designed for? I do empathize with you about it being an odd policy but if they designed it specifically to use tubes that their systems deem "The Best Tubes" and you go and use something different, why should their warranty cover your choice to disregard their design?
