Had a few 100KC crystal tubes like that for use in a marker generator for ham radio receivers. The smaller high-frequency TCCO's in the cans are pretty neat inside too. That stuff will run until it breaks if you've got the space.

The man voiceover is so familiar to me from old school documentaries and also from like Epcot Center rides

The crystals are sealed in glass tubes to assure stability. Interesting how they grew them years ago.

[@HiwasseeRiver]

The same process is still in use .

Some trusts were so integral to our nation that they should never have been busted. R.I.P. Western Electric and Bell Labs.
