Audio research reference 10 tube replacement

If I use this preamp 12 hours a day how long Will it take before I need to replace tubes?

I hear Macintosh preamp tubes Will last 9000 hours. Don't mind replacing a couple tubes but very expensive to replace all the audio research tubes.

Otherwise looks like a nice preamp

Audio research power amplifier is far better than its preamplifier, and due to 6h30 in the preamplifier,it becomes a hard job, cause 6h30 is a strong horse and I am wondering who can ride it well. I expect they change the drive tube in the ref 11 and then I will definitely go for it.
