ABSTRACT OF THE DISCLOSURE A power amplifier connection comprises a switching amplifier and a proportional amplifier. The output signal from the switching amplifier and the output signal from the proportional amplifier are supplied to a summation member which, by addition of the two output signals, forms the resultant output signal of the amplifier connection. The switching amplifier is adapted to be controlled in dependence on the input signal of the amplifier connection in such a way that its output signal endeavours to follow the input signal. The proportional amplifier is adapted to be controlled in de- pendence on the deviation between the input signal and output signal of the amplifier connection.
