Multistage Transistor Audio Amplifier Circuit

This electronics video tutorial discusses the basic elements of a multistage transistor audio amplifier circuit. It explains the importance of the bypass capacitors as it relates to voltage gain and distortion as well as the importance of the potentiometers for volume control and managing the input voltages. It also mentions the DC beta and hfe values of a typical NPN transistor as well as the purpose of the coupling capacitors. Finally, it discusses the efficiency of a regular common emitter transistor amplifier vs the class A transformer coupled amplifier.
