A source of pulses for the electronic suppression of pain is represented by a multivibrator wherein the amplitude of the output signal is double the value of the feeding voltage. The principle of the invention resides in a multivibrator provided with two sets of complementary pairs of transistors, one set of which works simultaneously as a switch and a feeder of voltage doublers. The multivibrator is fed by this increased voltage so that at the output, pulses of double amplitude arise, i.e. an amplitude four times greater than the value of the feeding voltage.
