Abstract: An audio amplifier having a low-noise input stage, being of a type which comprises a gain stage and an output stage cascade connected downstream from said input stage which includes first and second transistors having their respective bases connected to each other via corresponding input resistors, with the base of the first transistor also adapted to constitute a signal input for the amplifier, further comprises an electric connection between the collector of said second transistor and said input resistors to define a diode configuration for that second transistor, thereby the offset effect of the input resistors can be compensated for, and the noise voltage at the output from the amplifier downed.
