 EMI1.1 
 



   Es besteht ein Bedürfnis nach Empfangsgeräten und Verstärkern, die sowohl für Gleichstrom als auch, nach möglichst einfachen Abänderungen, für Wechselstrom verwendbar sind. 



   Der Erfüllung dieser Ansprüche dient erfindungsgemäss folgende Anordnung. 



   Es wird die in jedem Gleichstromgerät zur Beruhigung des Gleichstromes vorhandene Drossel mit einer mehrteiligen Wicklung ausgeführt. Die einzelnen Wicklungsteile werden, solange die Anordnung bei Gleichstrombetrieb als Drossel wirken soll, in der zweckmässigsten Anordnung, vorzugsweise hintereinander, geschaltet. 



   Die Wicklungsteile sind nun so dimensioniert, dass sie auch als   Primär-und Sekundärwicklungen   eines Transformators bei Betrieb des Gerätes mit Wechselstrom verwendet werden können. 



   Besonders vorteilhaft ist diese Anordnung, wenn beim   Gleichstromgerät   die indirekt geheizten Gleichstromröhren verwendet werden. Die Drossel führt in diesem Falle nur den Anodenstrom des Gerätes.

 EMI1.1
 



   There is a need for receiving devices and amplifiers which can be used for both direct current and, after the simplest possible modifications, for alternating current.



   According to the invention, the following arrangement serves to meet these claims.



   The choke that is present in every direct current device to calm the direct current is implemented with a multi-part winding. As long as the arrangement is to act as a throttle in DC operation, the individual winding parts are switched in the most expedient arrangement, preferably one behind the other.



   The winding parts are now dimensioned such that they can also be used as primary and secondary windings of a transformer when the device is operated with alternating current.



   This arrangement is particularly advantageous if the indirectly heated direct current tubes are used in the direct current device. In this case, the choke only carries the anode current of the device.
