  Article Content


The Compactron is a 12-pin vacuum tube invented in the early 1960s by General Electric in Owensboro, Kentucky with the express purpose of keeping tubes in the market for a few more years during the solid state revolution. Television sets were a primary application. Most Compactrons are either multiple tubes (e.g. three triodes in one bulb), or high-voltage and high-power types such as television sweep tubes.

A distinguishing feature of Compactrons is the placement of the glass nubbie on the bottom end, rather than the top end as was customary with "miniature" tubes.
