NIST (National Institute of Standards and Technology) 45 Record Player

Project Tinkertoy Wafer Tube Amplifier
Marsden, Charles P.
This artifact is a 45 rpm record player with a wafer tube amplifier. It was built at the National Bureau of Standards (NBS) as part of Project Tinkertoy, a Navy Bureau of Aeronautics sponsored project to develop mechanized production of electronic equipment using standardized components. The record player was built to show the feasibility of the standardized wafer tube. The player has 3 tubes, one of which is a ""glass-front"" tube so that the inside construction and hot cathode can be seen. The player is mounted on Lucite box with a power supply and amplifier visible. Also visible are plastic-encapsulated cross-sections and a complete tube, and multivibrator circuits complete with circuit and 2 tubes. A cross section of the wafer tube stack is assembled in the carrier. The carriers were passed through the high vacuum processing machine ""monster"", entering and exiting at atmospheric pressure. It was in use from 1954-1958.
