Welcome To Steve Johnson's
Supreme Instruments Collection

Welcome to my Supreme Instruments collection. This site contains photos of over 75 different Supreme models in my collection and various manuals, schematics, catalogs, ads, history, and information about Supreme's tube testers, radio analyzers, meters, and other radio test equipment manufactured by Supreme Instruments Corporation in Greenwood Mississippi.

I collect items mostly from Supreme's early years (1920's-1940's) although you will find items from the 1950's listed here also. I also purchase Supreme related items and offer free downloads of Supreme manuals, diagrams, schematics, and tube tester data sheets.

I would like to thank everyone that has sent me Supreme equipment and literature to post on this site as a resource for other test equipment collectors.

Supreme Tube Tester
The Supreme 85C countertop tube tester above was designed to sit on a radio store's front counter and allowed the customers to test their own tubes.
