The integrated circuits used in this oscillator are not very common today, as we obtained it in documentation from the 1980s. The circuit must be powered by a symmetrical source.
We found this simple transistor tester in a French publication in 1981. It uses a common analog...

This circuit is from an 80's component manual. The components are from the time, but the circuit...
