Abstract
An adjustable output transformer using a pair of adjacent facing pot cores, the first of which carries both primary and secondary windings, the second having only a shorted winding around one leg. The shorted winding inhibits flux through its leg and the corresponding portion of the adjacent leg on the first core so that the secondary voltage may be varied by adjusting the relative rotational positions of the two cores and hence the amount of flux linking the secondary winding.
