Oscilloscope PM 3110 Philips : une panne curieuse
by Roland Lorieux.
I am a faithful subscriber to Radiofil magazine which I appreciate very much and I wish to contribute towards maintaining its technical level. This why I decided to submit an article describing a fault on a Philips PM 3110 oscilloscope and its repair, which could be of use to hobbyists.
I am working on more descriptions of my radio restorations so that I can share them. But this takes a lot of time. I believe that this effort is required in order to maintain our analogue knowledge which is at risk of disappearing with the last enthusiasts of our generation.

Les redresseurs au sélénium
by Pierre Barrat.
These are components which are not rare in valve equipment from the 50’s. Now, after having replaced several with silicon diodes following tests I’d carried out, I began to wonder why HT cells were always defective whereas BT cells were always ok.
Refaire un bandage de galet de tourne-disque
by Bernard Dailly.
Who has not at some time had to deal with this type of problem for the model of roller on a record player as shown in the photo of figure 1. Here is a little tip for its restoration. Being an intermediate roller, the external diameter is not critical because it has no effect on the speed of rotation of the turntable.

Ampli à tubes EF86/EL84
As most of you know, the Radiofil forum, which is open to all vintage radio and audio enthusiasts, is a hub of good natured discussion and exchange and therefore an invaluable source of information, with regular participation from other countries. We select subjects which we believe will be of great interest to our readers and publish them in the magazine, with particular consideration for those who don’t have Internet. In this edition we look at valve amplifiers using the EF86 and EL84.

L'Ecole Centrale d'Electronique
by Daniel Maignan.
The School, better known as “ l’École de la rue de la Lune ”, was founded by Mr Lavigne who was a radio instructor at “ l’École de la TSF de la Marine ” in Toulon during the First World War.
In 1919, the war having ended, he had the idea to start a course aimed at training radiotelegraphy operators.
Wireless was still an emerging technology, and for a long time the School remained the only one for training civil and military radio operators.

Le poste Zenith 9S324 de 1938
by Jean Cudraz.
Here’s a lovely set from the other side of the Atlantic with a different design to those of ours in Europe. The cabinet, with no rear cover, is of varnished wood and has cut-outs on the left hand side for the 21cm loudspeaker.
Faites chanter toutes vos TSF à l’unisson
by Gérard Chevaillier.
I invite you to be able to hear your own music throughout the house on your beloved wireless sets. To do this, I took the inspiration from a circuit which appeared in Retro-Phonia magazine No 13 to make up this small, very low power, transmitter working at 1MHz. You can then receive music on the SW band of your wireless sets.
