Found in a 1980s documentation, this circuit makes use of components from that time. Modern equivalents can be tried out.
We found this circuit in a 1976 FET documentation. The circuit can be used to oscillate at other...
This conventional version with a transistor, already explored many times on our website, was found...
The circuit shown is from a 1972 publication. Transistors can be current types like 2N2222. The...
