 und der Nullinie gelegt, und die   Arbeitskennlinie   wird so gewählt, dass Verzerrungen, die durch die Krümmung der Verstärkerkennlinie entstehen, durch die Krümmung der   Gleiehrichterkennlinie   kompensiert werden. Im Anodenkreis des Verstärkers kann dann ein formgetreues,   verzerrungsloses   Kurvenbild der zugeführten Ströme abgenommen werden. 



   Fig. 3 zeigt ein beispielsweises Schaltschema der Endstufe eines   B-Verstärkers.   Der Arbeitspunkt wird durch Regeln der Gittervorspannung G eingestellt. Die Diode D im Gitterkreis schneidet die eine Hälfte der über den   Transformator ?'übertragenen Wechselspannung   ab. Dire Kennlinie ist dabei so eingestellt, dass sie in der oben beschriebenen Weise eine Kompensation der Verzerrungen herbeiführt. 



   PATENT-ANSPRÜCHE :
1. Schaltung für B-Verstärker, in deren Gitterkreis ein Einweggleiehriehter angeordnet ist. dadurch gekennzeichnet, dass die Kennlinie des Gleichrichters so gewählt ist, dass Verzerrungen, welche durch die B-Verstärkerkennlinie entstehen, durch die Gleichrichterkennlinie ausgeglichen werden.

 and the zero line, and the operating characteristic is chosen so that distortions that arise from the curvature of the amplifier characteristic are compensated for by the curvature of the equilibrium characteristic. In the anode circuit of the amplifier, a true-to-shape, distortion-free curve image of the supplied currents can then be obtained.



   Fig. 3 shows an exemplary circuit diagram of the output stage of a B amplifier. The operating point is set by regulating the grid prestress G. The diode D in the grid circle cuts off half of the alternating voltage transmitted via the transformer? '. The characteristic is set in such a way that it compensates for the distortions in the manner described above.



   PATENT CLAIMS:
1. Circuit for B-amplifiers, in the grid circle of which a one-way slide is arranged. characterized in that the characteristic curve of the rectifier is chosen so that distortions which arise from the B amplifier characteristic are compensated for by the rectifier characteristic.
