It's time to set up the assembled single-ended tube SE amplifier with a transformer wound for it, to show the reasons why this amplifier, assembled according to the classic, proven scheme, did not produce the declared parameters. After setting up, I will test the amplifier using the Shmelev measuring complex. And finally, I will tell you what else needs to be done to improve the sound of the amplifier. *** You can help in the development of the Channel: Yandex Money: https://yoomoney.ru/to/410013004521132 Web Money: Z546631268395 *** Links to the video: "Tube SE amplifier.
