Improvements in the intermediate frequency sound amplifier circuits and frequency detector in television receivers, characterized in that the coupling between the video amplifier and the intermediate frequency sound amplifier is carried out by means of a double tuning circuit and high Q value. , constituted by a series resonant circuit connected to a parallel resonant circuit, both tuned to the value of the intermediate frequency to be amplified, the coupling of both circuits being carried out in two ways: inductively, by the physical situation of the respective inductances, and capacitively, by means of a transfer capacitor, its output being applied to the base of the first intermediate frequency amplifying transistor.
