Improvements in the tuning devices with built-in adjustment mechanism, essentially characterized in that the transmission of the turning motion to the tuning axis of a variable capacitor is alternatively made by a tubular shaft with direct and fast kinematic coupling and by an inner and coaxial shaft to the previous one and of slow and indirect kinematic coupling, the former involving a cogwheel integral and meshed with an analog wheel mounted on the tuning axis, which allows the rapid rotation of the latter by actuating it, while the central shaft carries integral at its end a cam whose rotation originates that of a lever of first gender, supported by its central part and driven by the cam on its upper arm, while its lower arm receives the recovery action of a helical spring, whose other end is it is fixed to a static point of the receiver's body.
