Abstract
1. Line transformer for a television receiver having a primary winding bracket (5), a secondary winding (6) and two core parts (2, 3) which are placed together to provide an air gap, characterized in that the core parts (2, 3) are directly in contact, without air gap, over a limited part of their cross section and that an air gap (8), having a width which varies over the cross section, is provided over the remaining cross section.
