S&T GeoTronics makes quality Open Source retro tech replicas.  It's what we do: combining our passions for history, technology, and engineering to bring you these unique products. We believe in craftsmanship, being intimately involved with the making of a piece of art that is well-made, long-lasting, and desirable.

An identifying factor of our craftsmanship is our interest in the process of creating. The focus is on the product, the creative process, and how much enjoyment it brings.  We are dedicated to Open Source, and you can make what we make by following our instructions.

​

These machines are assembled entirely by hand, by us, in our very small workshop. We have no "mass production" equipment. Each wooden case is made from 3/8" selected imported wood, and fitted with the best materials we can obtain. These cases will last as long as the electronics they contain. We look forward to doing business with you.
