2N3055 with PCB Power Amplifier OCL 60W

This is Power Amplifier OCL 60W circuit. It is the circuit that gives bland excellent sound , because of use the transistor entirely (Hot part 2N3055 x 2) have no IC mix. Then may build difficult go to small but for what is the experienced person may have no a problem. For sound power that pay to come out about 60W at 8ohm size loudspeakers s build to sing can bail 12 inch sizes comfortablely. About story of the voltage supply for this circuit as a result the important. Should use the pressure about +/- 40V the trend doesn’t lower 3A .Other detail see in circuit picture.
