This video is about the output transformer of a single-ended - SE tube audio amplifier. When winding the output transformer for a single-ended tube amplifier, I will take into account several options for calculating the transformer in order to choose the best calculation in practice - according to tests. And at the end of the video I will show the difference between the hysteresis curve of the wound transformer and the hysteresis curve of the TN-36 power transformer.
