I haven't been keeping track of my Cronus Magnum tube hours so I'll probably just swap them out in a few years. Mine have relatively low hours because I listen mostly to my solid-state integrated for a good 8 - 10 hours a day in my office.
The Cronus Magnum gets special treatment and is powered ON only for those special sit-down and pay attention listening sessions rather than background music while I work. I've never had a tube outright fail in my Rogue gear.
I had a bad batch of EL34 tubes a few years ago in my Manley monoblocks and that was a bit of a pain. I had to replace a few cathode resistors under the chassis and at 70 Lbs each, it was a bit of work..... but I felt better about doing it myself vs trying to ship those beasts half way across the country for service. I replaced all 10 EL34 (per monoblock) with 6CA7EH and all was fine.
Overall I've had pretty good luck with tubes, no major catastrophes.
The Manley amps were a couple of THE best sounding that I have ever owned. But you know what? The Rogue is right up there at a fraction of the price.
