In this video, I will test various transformers, compare the results, and finally conduct a computer test of the output transformer, calculated and wound for a vacuum tube single-ended SE amplifier. I will show how you can easily compare transformers by their main characteristics and make the right choice of transformer for your audio amplifier. *** You can help develop the Channel: Yandex Money: https://yoomoney.ru/to/410013004521132 Web Money: Z546631268395 *** Links to the videos: "Hi Fi.
