É avalei 5 estrelas, vi que os componentes e a placa para montagem bem legível

For this price some compromises might be expected. A: The pcb is rather thin. The board-to-trace bond is not very strong, traces tend to lift off if soldering takes too long. B: Placement of fixing holes rather strange - one is located under a 2200uF capacitor! C: Finally the amplifier suffers from a fundamental PCB design fault. The rather narrow ground trace first goes from power supply capacitors through the center of the board to speaker connector, then to the input connector and last runs

es muy buen producto, fácil de ensamblar, los valores de las resistencias no tiene las especificaciones correctas, y no especifica que se nececita un transformador para alimentar el circuilto (FAIL) lo cual aumenta el gasto del kit y se pierde la buena relacion costo-valor. Aun no lo podido probar, pero espero y funcione bien.

Funciona perfectamente con muy buen sonido y bastante potencia. Sólo comentar que es conveniente aislar los orificios de los tornillos al montarlo en un chasis y además colocarles disipadores mayores a los IC's

All of the parts were in the plastic bag at one time, but when they arrived they were torn and messy. As shown in the attached image, capacitors are replaced with laminated film capacitors and tantalum capacitors. 47μF for feedback is intact. Since the power supply is a test with a bipolar power supply of ± 13 V DC, part of the filter capacitor is excluded. Product description is inadequate. In order to communicate it to beginners in an easy-to-understand manner, it is necessary to specify that

Recomendo a todos que querem montar um som e precisam de um bom amplificador mas não podem gastar muito. O TDA2030 é um amplificador bem versátil um ótimo custo beneficio.

Produto errado

Kit semplice da montare ed ottimo come qualita' e potenza acustica. Ideale per applicazioni amatoriali.

tudo certinho bem embalado ok chegou tudo ok recomendo essa loja e o esse vendedor valeu

After building was tested and working properly.
