In this preamplifier, it is proposed to connect bipolar transistors of in each case the opposite type of conduction (pnp and, respectively, npn) to one another with their collectors and to connect their emitters in each case via emitter resistors to earth or the supply voltage, the two emitters also being decoupled via capacitors in series with further low-resistance emitter resistors to earth in order to achieve a high alternating-voltage gain with low distortion.
