Dear Juha,

First off a bit of information. GDER ist not a tube brand, but an "approval" brand for French made tubes. Proceedings from the sales of tubes with the GDER logo on them went into the financing of the French radio broadcasts via the Compagnie Francaise de Radiophonie.

The type R5 is of La Radiotechnique, see the entry for the tube.

Without much better pictures of details one cannot say a whole lot about the receiver itself. What can be seen of the cabinet is that the sides recede behind the front plate, which is more unusual for an industrial fabrication.

The apparent lack of markings on the front plate are another indication that this set is probably a kit. The irregular spacing of drill holes is another.

You'd have to make better close-ups and specifically also show the wiring of the top and under the chassis, as well as component markings. Also the mounting of the reaction coil (?) would be good to show. The people can form a better opinion about your set.

Kind regards
Mark

other word it didn't belongs to this radio. this was making some holes.

also fron panel it is not dark bacelit it is like gold paint. not bad idea ;)

When I go back home I will add some pics. I think this is quite old one. 1923-25?

Dear Juha,

Ok, let's wait for some more pictures. The tubes are "old" of course, they have the TM shape and certainly are pre-1925 although that doesn't allow us to conclude anything.

Industrially-built receivers with interior tubes come up around 1925 with a few exceptions.

Kind regards
Mark

Hi.

This is certainly a Home -brew, like I have and been correctly identified by the unforgettable friend Konrad Birkner.
