RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB.

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.
