This circuit is from 1985 documentation. The integrated circuit is not very common today, but modifications can be made leading to a project with current integrated circuits.
We found this circuit in a 1967 Experimenters Handbook. The circuit can be implemented with other...
This circuit is from an old documentation but can be implemented with a BD136 for Q1 and 2N3055 for...
