Audio transformers are manufactured: 1. "Magnetek" cores of nanoperm. 2. Harness, about 22 meters long. Ten live copper wire 0.1. They are connected in series. End of the first section of the beginning of the second. The resistance of a section of the primary winding 45 ohms. When Rm = 10, 450 ohms, respectively. 3. On the same harness added two cores constantan wire 0.14. The resistance of each conductor of the secondary winding exactly 700 ohms.Total harness consists of 12 cores: 10 copper 0.1 and two constantan 0.14. Number of revolutions around 220.

Звуковые трансформаторы изготовлены: 1. Магнетековские сердечники из наноперма. 2. Жгут, длиной около 22 метров. Десять жил медного провода ПЭЛ 0,1. Они соединены последовательно. Конец первой секции с началом второй. Активное сопротивление одной секции первичной обмотки 45 Ом. При Кт=10 450 Ом соответственно. 3. В этот же жгут добавлены две жилы константанового провода ПЭШОК 0,14. Активное сопротивление каждой жилы вторичной обмотки ровно по 700 Ом. Итого жгут состоит из 12 жил: 10 медных ПЭЛ 0,1 и две ПЭШОК 0,14. Количество витков около 220.
