The module presents increases the intensity of the signals of amplifiers for automotive use, getting to have an output of 70Wrms. The amplifier has its activation done automatically, taking advantage of the circuit of the electric antenna. For the stereo version (70 + 70 W rms) it is necessary to mount two similar amplifiers and replace P1 and P2 with double potentiometers, in addition to doubling the currents of TR1, D1, D2, D3, D4 and F1, in addition to the values of C4, C6 and C7 of the power supply circuit. The amplifier's CI-1 integrated circuit and the power supply transistors Q4 and Q5 must be mounted on good heat sinks and electrically isolated from them.
