I have some of my own opinions and ideas on this subject. To me, the glassworking aspect is the most difficult part of the entire process. From what I have been reading, the high temperature bakeout is not strictly necessary, and is mostly to get shorter pumpdown times. There is no economic pressure to get product shoveled out the door quickly, so doing low temperature bakeout could cause fewer problems related to that. Also, there are improved diffusion pump oils and vacuum pumps available now that will help get a better vacuum than was possible in the past. Why settle for good enough if a better result is possible and would pay dividends in longer tube life?

It seems to me there is a bit of impatience growing in the vintage TV community about not being able to get a CRT rebuilt. Not on my part, but only stating what I have seen lately.
