We found this circuit in a 1965 Electronic Design. Transistors are still common but admit equivalents for some of them. The circuit drains a current of only 4 mA.
This traditional unijunction transistor configuration was found in a 1980s documentation. The functions are...
Found in a 1964 Electronic Design, this circuit uses transistors from that time. Equivalent...
