Abstract

824,647. Transformers. BRITISH BROADCASTING CORPORATION. June 12, 1956 [June 17, 1955], No. 17619/55. Class 38 (2). A transformer, suitable for use in a pushpull amplifier circuit employing negative feedback, comprises a main primary and main secondary winding and an auxiliary primary and auxiliary secondary winding, all the windings being on the same limb of a core and the two primary windings being connected in parallel between terminals T 1 , T 2 (T 5 and T 6 being strapped together). The output from the auxiliary secondary winding taken at T 9 , T 10 may be used as a feedback voltage. The output from the main secondary winding is derived from terminals T 3 , T 4 , T 7 , T 8 which may be interconnected in various ways. The windings are constituted by various sections such as P 1 ... P 12 , FP 1 and FP 2 , details of which are given in the Specification.
