Custom Secondary Coils

Tesla Secondary Coils

We now offer a full array of custom secondary coil winding services. We offer a wide selection of custom wound secondary coils in a variety of secondary coil diameters as well as magnet wire sizes ranging from 20 AWG to 36 AWG. Our secondary coils are wound use high quality enameled magnet wire on Type I PVC coilforms which have superior dielectric strength, perfect for high voltage secondary coils. All coilforms have a wall thickness of 0.062" and come with birch plywood end plates. Secondaries are provided uncoated. Allow 1-2 weeks delivery time for custom secondaries.

When ordering, please specify the winding length of each secondary coil. Each secondary by default will be made with approximately 0.5" extra coilform on each side of the winding. For example, if you order a 2.3" DIA secondary with 12" winding length, you will receive a secondary coil with a total length of approximately 13", of which the 12" magnet winding will be centered. If you wish to have a different type of configuration, please contact us before ordering.
