I just hope they do their research and make very robust versions of whatever they decide tp make. I don't know about the current reissues, but, the 300bs made in the 1990's are terrific. I know people who still run their tubes daily that were purchased more than twenty years ago.
I run old Western Electric 310As, 348 and 349 tubes that were old pulls when I got them (who knows how much use they had), and I am still running the same tubes 15 years later.
