Abstract

Set of tuners for television receivers composed of a VHF channel selector, a UHF tuner and means for switching the power of some anodic circuits corresponding to said tuners, wherein said channel selector comprises a high frequency amplifier step , a mixing step and an oscillator pitch and said UHF tuner comprises a high-frequency amplifier passage and a self-oscillating converter passage, and said means are substantially constituted with a switch with external control that allows to suppress the anodic supply of said steps amplifier and oscillator of the VHF selector switching it to both steps of the UHF tuner and vice versa by means of said external control; the whole being characterized by the fact that the intermediate frequency output of said UHF tuner is connected, by means of a shielded cable, with a bridge circuit LC forming part of the channel selector, said circuit being able to transfer the signal of intermediate frequency from the UHF tuner to the input of the VHF converter step, and also constituting the secondary of a band filter capacitively coupled by the base and by means of said cable to a primary located in the UHF tuner, and being balanced with relation to the high frequencies coming from the previous step of the channel selector by means of a capacity bridge.
