We found this circuit in a 1979 French publication, but it can still be assembled today with equivalent components and with the changes we have made. For T1 we can use a BC547 and for T2 a BD135. The transformer is 20 + 20 V with 1 A and the rectifier diodes can be the 1N4004. The output transistor must be provided with a good heat radiator.
