A NEW plate choke design:
... Use one of the following forms; A hollow ceramic tube at least 6" long with an ID of at least 1/2". An O.D. of 1" or more. The wall thickness should be no less than 1/16th", more is better, but not thicker than 3/8ths". The same parameters apply to materials like electrical grade fiberglass, Delrin® ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
