Hello
I'm the lucky owner of the radio mentioned in topic (see attachments) but unfortunately there's only few information about it in the net.
My set is almost (I hope) complete, but there is probably one piece missing (coil, choke, transformer?) and one added (condenser) - this I could see by comparison with available photos (rmorg).
If anyone has any information, detailed photos or schema - everything could be helpful in restoration.

Hello,

it seems, that this case will be very complicated.

Which model is it exactly?
There was a model 23LG and a model 23LW.
LG stands for DC and LW for AC.

Your picture shows 3 tubes. That should mean, that you got the 'LW' version. Even the RMorg has no wiring diagram.

As an exception, the small pictures at RM.org are able to enlarge.

The third tube is possibly a rectifier. But then, the radio shown in the picture should be the model Tefagon 23LW.

The only chance is to search for a similar radio with an almost similar schema.

Maybe the people at wumpus do know something more.


Greetings

It's model 23L (without W or G) - I'm sure because there is a badge with such a sign and a paper sheet with the data of maker, controller and datums of this activities (22/24.11.1930). There is also (under the cabinet a kind of dry battery and connections to it signed "gitterbaterie" - did anybody see such a solution?
I'll try at other forums

In "Katalog Radio Zentrale Prohaska 1930/1931" this set is listed No. 3063 on p.19
Since it has 3 valves, it is definitely the 23L for AC.
Text translated:
Mains receiver with magnetic speaker for reception of main radio stations, some distant stations with a good antenna only, 1 audion, 1 AF stage RC coupling, capacitve reaction. Range 200 - 2000 m; change of coils necessary. Input for grammophone. In nice modern case of kaukasic nut, 38*38*16 cm, included coils for 200 - 2000 m.
a) for DC 220V Mark 115,-- (valves excluded); Valves: RE084, RE134 Mark 21,50
b) for AC 110 & 220V Mark 100,-- (valves excluded); Valves: REN1004, RE134, RGN1500 (rectifier) Mark 34,--
------
On those days, rectifiers were not counted, therefore, this was a 2 valve set.

This is a very simple set, probably comparable to "Volksempfänger" VE301

Thank you for response and information delivered - surely its 23L (3 valves ren 904, re 134 and another re 134 (mistaken or intentionally used as a rectifier) designed for 110AC as written on the label.
