5965

The 5965 is a miniature twin triode vacuum tube "designed for use in high-speed digital computers".
According to an MIT Project Whirwind memorandum, the tube was developed c.1953 for IBM by GE, primarily for use in the IBM 701 computer, and was designated as a general-purpose triode tube.
In European use the tube was labelled E180CC; sometimes the same tube was labelled with both names.
