The 5965 is a miniature twin triode vacuum tube (thermionic valve). According to its manufacturer, Sylvania, it was “designed for use in high-speed digital computers”.[1]
According to an MIT Project Whirwind memorandum, the tube was developed for IBM by GE, primarily for use in the IBM 701 calculators, and was designated as a general-purpose triode tube.[2] The tube was also labeled as E180CC.[3]
