5965

The 5965 is a miniature twin triode vacuum tube (thermionic valve). One of its manufacturers, Sylvania, states that it was “designed for use in high-speed digital computers”.

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. The tube was also labeled as E180CC.
