Some say that if you connect this as instructed. On this occasion I built this 4-1 Balun for a single use. The Transformers. How to Calculate Toroidal Transformers. It's an accurately and reliability digital toroid-winding machine. I want to modify it to have two 220 volts outputs instead the two 40 volts outputs that it has at the moment. Using toroid transformers one can make a test amp to try out and whilst not as good as using custom transformers should still perform more than adequately and prove the concept. It transforms electrical energy from one circuit to another with the help of mutual induction between the primary and secondary windings. A part of the winding is common to both primary and secondary sides.
