Home Audio Tube Amplifier
Written on Apr 2nd, 2010
Back when I was about 20 years old, a friend of mine living in the same building at UBC as me ending up building a little do-it-yourself audio tube amplifier for home. It was one of the coolest looking devices I have ever seen, and made me really want to try putting something like that together. When most people think of vacuum tubes, then think of outdated technology from the 60s that was generally inferior and not long lasting. That was typically true of a lot of audio applications back in the day unfortunately. That said, while the vacuum tube has mostly been replaced by the transistor, there are still many applications that make use of vacuum tubes, such as high end audio, especially in guitar amplifiers. From a purely mathematical point of view, vacuum tubes produce a great deal of distortion when compared to transistors. What the math fails […]
