In this circuit we have the way to use two transistors as a regenerative pair simulating an SCR. The circuit is from a 1965 General Electric documentation.
The frequency depends on the coil and is not found in the original documentation but should be...
This is a device for those who need to show that they know how to use digital electronics but have...
Using an operational amplifier with FET, this circuit from a 1977 publication can generate...
