South Texas Amp Co. was established by Pete Mitchelltree & Richard Smith out of our love for thermionic amplification and not as a primary business. Our goal is to provide only the finest quality in custom built & amplification repair. We have our own CNC machine to precission mill our custom chassis.

Our amplifiers are not simply copies of classic circuits. We spend most of our time researching, refining, and breadboarding our circuits. What may work on paper or in software might not sound so good in the real world. We developed Protozilla which is a point to point thermionic breadboard so we can easily build and manipulate circuits long before building the final product.
