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.
