 durch die Ventilröhre   V2   verbraucht werden, so dass also die Möglichkeit besteht, die   Gleichstromverhält-     nisse   in der   Besprechungsröhre   M nach Wunsch zu regulieren. In den Schaltungen sind als Ventilröhre Dreielektrodenröhren angegeben, es können   natürlich auch   Zweielektrodenröhren oder aber Röhren mit mehr Elektroden verwendet werden. Auch kann die vorliegende Erfindung bei anderen Schaltungen als dem gezeigten   Ausführungsbeispiel   natürlich Verwendung finden. 



   PATENT-ANSPRÜCHE :
1. Schaltung für Röhrensender, bei der die   Beeinflussung   der Gitterspannungen mittels einer Modulationsröhre erfolgt, welche vom Gittergleichstrom der zu steuernden Röhre durchflossen wird, dadurch gekennzeichnet, dass ausser der zur Modulation dienenden Röhre noch eine besondere Ventilröhre vor- gesehen ist, welche zwischen Gitter und Kathode bzw. zwischen Anode und Gitter der zu steuernden
Röhre angeordnet ist.

 are consumed by the valve tube V2, so that there is the possibility of regulating the direct current conditions in the meeting tube M as desired. Three-electrode tubes are specified as valve tubes in the circuits; of course, two-electrode tubes or tubes with more electrodes can also be used. The present invention can of course also be used in circuits other than the exemplary embodiment shown.



   PATENT CLAIMS:
1. Circuit for tube transmitters in which the grid voltages are influenced by means of a modulation tube through which the grid direct current of the tube to be controlled flows, characterized in that, in addition to the tube used for modulation, a special valve tube is provided, which is located between the grid and Cathode or between the anode and the grid to be controlled
Tube is arranged.

Claims (1)

2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, dass als Ventilröhre eine Dreielektroden- röhre verwendet wird. 2. Arrangement according to claim 1, characterized in that a three-electrode tube is used as the valve tube. 3.
