I've built quite a few devices using the IV-9 tubes, and found them to be extremely durable. (I probably wouldn't be interested in a clock kit, as I have about 3500 tubes in stock...) If operated below their maximum operating parameters (dimmed a little, and soft-started filaments), they'll run essentially forever. The DTF-104Bs are even better, and are really fantastic-looking tubes. They're also extremely rugged mechanically. I've built Burning Man Mutant Vehicle dashboards using these, and the rather extreme conditions of that application didn't faze them at all. I've also had clocks running for nearly a decade with exactly zero failure due to the tube burning out. Impact with flying objects is another matter, but in fact a tube survived for a minute or two even with its outer glass envelope completely shattered. Again, if operated within their specified environment, their lifespan is essentially unlimited. ~~ Mark Moulding
