of us like seeing the old advertisements from vintage era magazines.
This Taylor Tubes advertisement from the February 1941 edition of
the ARRL's QST magazine is a prime example. Vacuum tubes had a high
degree of automation for stamping out internal components, forming
the glass shells and evacuation of the air, but they still required
human production line operators for assembling the components prior
to being encapsulated and sealed. National Instruments hadn't invented
LabVIEW yet to run the testing station, so people manually placed
the tubes into a board full of sockets for burn-in and testing.
