function as a relaxation oscillator whose frequency can be adjusted between 5 kHz to 30 kHz, the potentiometer P1. Q and Q outputs of each section are applicable to each of the non-inverting amplifier 4050 type, IC2 and IC3. Each of the six stages of the integrated circuit, connected in parallel, allowing direct attack transistors T1/T2, respectively T3/T4 T1 or T2 and T4 and T3 simultaneously. These pairs of transistors can attack the piezoelectric speaker. Circuit provides a 15-18 Vdc
