Lundahl Transformers new nanocrystalline C-cores from Japan. “We have been looking at nanocrystalline C-cores before, but we have not been satisfied with their quality. These kids looks so much better!!! Initially we plan to develop an interstage and a line output transformer using these C-cores.”
On the previous nanocrystalline C-cores, the cut surface was not flat and well-polished. As a result, the core air gap was not well defined enough.
