I've been going with NOS tubes and they've lasted years. I have a pair of JAN's that are still alive after two years.
The big question is "Do you power off the M3A or use the stand-by mode?" I don't. I leave everything on all the time. All The Time.
My cdp has been on 5yrs and has never had a problem. Electronic gear doesn't like powering up and down.
