Tube life is dependent on more than just the hours used-
though that is a great place to start-
Input tubes - 12A_7, 6DJ8, and the variants should be good for 10,000 hours of run time
Power tubes are less - but here we really get into the circuit-
If the tube is biased hot, then start the subtraction machine...
The Old Quicksilver amp based on 8417 output tubes might last 6 months per pair -
At the other end, McIntosh and early Marantz could easily deliver years of enjoyment from a set of output tubes.
Happy Listening
