Life expectancy of both rear M4 tubes..

Had a tube go out in my RT2/50 today, so I'm gonna order some spares. What's the life expectancy on the rear M4 tubes?

Also, both my M4s came stock with 12AX7-WA tubes, but the positions are marked 12AX7, and 12AT7. Should I order the proper tubes? Or just stay with 12AX7s?

Lastly, are the stock Sovteks a decent tube for there? Or should I upgrade to something better?
 
If I recall correctly, Jeff said that they now ship the M4s with 2 12AX7s and not to worry about the 12AT7.
 
Klark - I'm assuming the M4 has an "input" V1 tube, just like the mod50.

I found a great NOS tube to put in that first slot, and it really did make all the modules sound even better.
