^^It's hard to be exact George but for Power Tubes they should last between 2000 - 3000+ hours, depending on how hard you use the amplifier.
The Preamp Tubes should last between 3,000 and 5,000 hours.
I am very impressed with this company so far, tomorrow or Friday I'll phone and ask about the 12AX7's and 12AU7's to get some info before ordering again. I want the Warmest possible tubes with the best bass response at modest volume.
Here's the link to the online shop.
