Abstract: A high voltage transformer for a television receiver includes a coil former supporting a primary winding on a magnetic core. The primary winding has an axial length L. A compartmentalized coil former supports a high voltage coil radially surrounding the primary winding. The high voltage coil has a radial outer diameter D with the ratio of L/D being less than one. A plurality of diodes are supported by the compartmentalized coil former and connect the high voltage coils in series. The diodes are supported on the compartmentalized coil former at substantially the same axial position and are equally spaced about the periphery of the compartmentalized coil former.
