Self Oscillating Amplifier for Distortion Testing


Posted on Jul 13, 2012

The circuit is based on a simple inductor-capacitor filter circuit, and needs only a pot and a small light bulb to set and stabilise the oscillation. The frequency is fixed, and with a good inductor should be capable of very low distortion. This circuit is a slight modification of that submitted by Alfred Schaub - I added a 100 ohm fixed resistor and used a 1k pot (rather than a single 100 ohm pot), and I also added a 1k resistor to improve the circuit`s Q and reduce externally generated distortion to the lowest possible.
