There are a lot of 'ifs', if the tubes are clean, biased right, warmed up right, run on a moderate load with moderate powers, if there is good air circulation, etc., then 10,000 is the expectation. We have seen this happen a lot over the last 20 years. Sometimes a tube is marginal from the factory and does not hold out all that long, other times the tubes go well in excess of that- we've seen over 20,000 hours too.
