Circuit Specialists

Circuit Specialists started out in Darrel and Leon Thorpe's garage in Scottsdale, Arizona back in 1971. By September of that year Circuit Specialists had moved into a small office and published its first mail order catalog, called "Semiconductor SuperMart," which featured resistors, capacitors, diodes, chokes, coils, and newly invented integrated circuits (ICs) as well as other products for electronics hobbyists and do-it-yourselfers.
