Neither have I, but that is not any type of guarantee.
In my view, all Russian 300B tubes seem to come from the same factory. Thus quality-wize, it might vary with the batch (sourced materials and workers skill).
Furthermore, we would need to know about the experience of normal audiophiles, i.e. people who have a pair of 300B in their (known) amp, and just liste to them for some period of time (i.e. "had them for over a year", "used those tubes more than 1000 hours", etc.).
With all frankness, I rarely listen to the same pair of output tubes longer than a week or two... not to mention to the same amp... wich obviously does not make me a good source for longevity related information.
