Welcome to Catahoula Technologies.
We offer products for hobby electronics enthusiasts and antique radio collectors.
Here you will find PCB kits for hobby electronic projects, and
reproduction parts to complete antique radio restorations including knobs and dial scales.
We offer custom services! If there is an interesting circuit that you would like to see a PCB designed or a reproduction antique radio part that you are looking for, please contact us
to discuss possibilities. We can make molds of hard to find knobs and pushbuttons when there is an existing part available to copy and then cast new resin parts.
We have a CNC router and lathe to fabricate wood knobs or cabinet finials. New parts are not 3D printed.
