The new owner of the Western Electric brand (he bought all the rights and manufacturing equipment and tools) has a new plant in the town where I live. There is much hand work that is done, but he has also invested a lot of newer equipment, like newer technology vacuum pump, to get less air in the tubes, to help give longer life for the 300B tubes they are producing. New tools to have tighter specs and control over the whole process. Bruce Quote Link to comment Share on other sites More sharing options...

It is a good thing that old but superior technology doesn't go to waste. Verstuurd vanaf mijn 5047U met Tapatalk Quote Link to comment Share on other sites More sharing options...
No.4 Posted April 28, 2019 Share Posted April 28, 2019 What a cool video! Those people are artists. The glass work looked effortless, however I suspect many years of practice has gone into that process. Quote Link to comment Share on other sites More sharing options...
edmjm Posted April 28, 2019 Share Posted April 28, 2019 I’ve always been told to not touch the glass because the oils on my skin can damage/weaken the glass when heated yet the only person to touch the tubes with gloves was the final packer. great video 1 Quote Link to comment Share on other sites More sharing options...

IMO unreliable tubes are the cause of early tube failures (or run near/above the operating limits). If touching the tubes with bear hands makes them live shorter lives, I wonder how many decades they would last if I never touched them? I think this one is a bit of anus audiophilia nervosa and not likely based in any real world truth. Now if you just finished eating a plate full of BBQ ribs you might wash your hands first but I doubt there's much merit to it otherwise. I DO find that gloves CAN assist in keeping the print more intact with vintage tube chalk labels but even that's tricky as some of the chalk labels can be really fragile. 1 Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted May 3, 2019 Share Posted May 3, 2019 Having replaced a few thousand tubes over the decades in radios and televisions which often trapped a huge amount of heat I can tell you that the oils on my fingers did not in any way shorten their life span!
