This circuit with unijunction transistors was found in a documentation from the 80's. The trigger times of the SCRs depend on the capacitors and are adjusted in the 5M (4M7) potentiometers.
In the figure we have a simple amplifier stage with a temperature compensated general purpose...
We found this circuit in the 1982 SGS Linear Integrated Circuits manual. The transistor supports...
