Claim:
1. A method of providing a portion of a transformer comprising: forming a core of the transformer by: providing transformer core material, cutting individual laminations from a single sheet of material, bending each individual lamination, one individual lamination at a time, into a generally C-shaped member, after the bending, stacking certain of the members to define a first core portion having a main leg and two opposing end legs, after the bending, stacking other of the members to define a second core portion having a main leg and two opposing end legs, arranging the main legs of the first and second core portions in a back-to-back manner to define the core having a core leg defined by the two main legs, and opposing core yokes, defined by the opposing end legs of the first and second core portions thereby eliminating a core annealing process in forming the core, and winding conductive material directly around the core leg to form a primary winding and secondary winding in any order of arrangement, thus providing a first transformer portion.
