An amplifier with gain regulation for use in a television signal processing circuit that includes a first and a second transistor, each having an ac gain that is a function of the direct current passing through it, said transistors having first and second collector to emitter connections in a series bias circuit with direct current, said amplifier being characterized by first means for coupling in cascade to said first and second transistors for television signals, second means coupled to said circuit in series for modifying the direct current that this series circuit travels, in order to modify the gain of said first and second transistors for said television signals, at the same time that the bandwidth is kept substantially constant.
