An improved circuit arrangement of transistors comprising a transistor amplifier coupled to direct current and, at least, a preceding stage carrying a pair of transistors coupled in the form of long tail pair or with persistent echo, characterized in that the polarization the base supplied for said transistors of the persistent echo pair is derived from said amplifier coupled to dc, said base supplies being determined by equal multiples of the voltage available at the junctions of the transistors incorporated in said amplifier coupled to dc.
