How Amplification Works (All of It)

Video edits together material from my other videos to do a complete run down of electronic amplification, from the origin of vacuum tubes, Class A, Class B, Class AB, Class D, op-amps, negative feedback and more, all carefully put together to make a seamless whole. Enjoy! You can get early, ad-free episodes and more for only $1 at   / notareviewchannel   Includes material from: Does Feedback Actually Ruin Sound? All Op-Amps Are Not Made the Same Can Op-Amps Beat Discrete Designs? Class AB Amplification Gave Me a Stroke Why Class D Breaks My Brain Enjoy! 0:00:00 Intro 0:01:40 Vacuum Tubes and Amplification 0:05:12 Single-Ended Class A 0:09:10 Class B part 1 0:10:23 Silicon and Doping 0:12:41 Transistors 0:17:46 Class B part 2 0:19:59 Conventional Current 0:20:31 Class AB with Transistors 0:24:23 Class AB with Tubes 0:28:11 Push-Pull Class A 0:31:44 Negative Feedback 0:36:57 Op-Amps and ICs 0:44:20 Discrete Op-Amps 0:44:53 Buffer Stages 0:50:56 Intro to Class D 0:52:45 How Class D works 0:55:24 Square Waves and Harmonics 0:58:05 Class D and Efficiency 0:58:36 GaN transistors 1:00:09 Load Dependency 1:01:51 Outro
