Technical pages :
L'amplificateur du Cercle by A. Cayrol.
The description of an audio frequencies amplifier which was used by a student association in Lille during the 1940's. This device was realized by one of the students.
La détection à réaction vous connaissez ? by D. Falgoux.
A short survey of the basic principles of regenerative circuits along with some useful advices concerning the realizations.
Une panne sournoise by P.-G. Henry.
The trouble of a 1940s GMR "Cricket" was due to unsticking of the four tuning cores, from their threaded bakelite bearers, in the IF transformers. Alignment was therefore impossible. Four drops of glue fixed this set which recovered its youth.

History of men :
Qui était Reinartz ? by Terry Pool.
This paper, written by Terry Pool, is a translation of his article "Who was Reinartz" published by our friends of the H.R.S.A. in the January 2000 issue (71) of their bulletin Radio Waves. We are indebted to Mr. W. Woods, president of the H.R.S.A., for the permission to reproduce this study in the columns of the A.E.A. Bulletin.

Atelier :
Retour sur le Synfonic Radio by Jean-Paul Cipierre.
In the last issue of our bulletin, D. Falgoux described a receiver with only two tubes in a superhet disposition. Here is exposed a practical discussion and an example of a home brewed realisation of such a receiver by J.-P. Cipierre.
Une vilaine panne de MF by J.-C. Montagné.
When a IF transformer wound with litz wire has some trands unsoldered at on end of the winding, one find a parasitic capacity and a difficulty to obtain the good tuning.
