Taylor Tubes Advertisement
February 1941 QST Article

February 1941 QST
February 1941 QST Cover - RF Cafe[Table of Contents]These articles are scanned and OCRed from old editions of the ARRL's QST magazine. Here is a list of the QST articles I have already posted. As time permits, I will be glad to scan articles for you. All copyrights (if any) are hereby acknowledged.
Some 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.
