Zusammenfassung:In a power amplifying device comprising a linear push-pull amplifier the transistors of which are mounted in a common emitter arrangement, the difference between the d.c. supply voltage and the variable peak voltage Vm appearing on the collectors of the transistors for each period of the input signal, is maintained constant through supplying to the amplifier a d.c. supply voltage Va equal to Vm + VD where VD is a predetermined voltage.
