In this video I will not only show you how to build a proper vacuum tube amplifier, but I will also directly compare it to a transistor amp. You will hear the audio quality difference between them and I will also show you the difference between them by using an FFT and also by creating a Bode plot. Along the way you will learn all about tube amplifiers which come with a proper tube output stage as well as a transformer. Let's get started!
