This article describes the Low Distortion Wien Bridge Oscillator (UA741). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:UA741.

This Wien bridge oscillator uses incandescent lamp to stabilize its amplitude. This amplitude stabilization gives a low distortion output.? Multiple frequency range selector gives flexible and fine adjustment for the frequency. Here is the schematic diagram of the circuit:
