FIELD: radio engineering.
SUBSTANCE: invention relates to the radioelectronic industry. Proposed to realise the technical result is a transistor electrical signal amplifier for shaping the amplitude frequency response of a signal reproduction amplifier providing an amplitude frequency response in the frequency range from 2122.1 Hz and higher, corresponding to the RIAA standard for amplifiers applied in the reproduction of long-playing gramophone recording of modern records. The equalisation type is an LR high-pass filter with a time constant τ2=75 ms, wherein: L is the constant inductance; R is the source-drain dynamic resistance of the field-effect transistor.
EFFECT: lower weight and size characteristics and higher reliability of the RIAA equaliser.
