• In vacuum tube audio amplifiers, center-tapped transformers were sometimes used as the phase inverter to drive the two output tubes of a push-pull stage. The technique is nearly as old as electronic amplification and is well documented, for example, in The Radiotron Designer's Handbook, Third Edition of 1940. This technique was carried over into transistor designs also, part of the reason for which was that capacitors were large, expensive and unreliable. However… WebOct 6, 2024 · Constructing Dual Power Supply Circuit: Step-I: Converting 220v AC into 12v AC using Step Down Transformer The primary terminals of the centre tapped transformer is connected with household supply (220V ac, 50Hz) and output is taken from secondary terminals of the transformer.
