TPA3116D2 2.1 Digital Audio Amplifier Board Subwoofer Speaker Amplifiers DC12V-24V 2x50W+100W
US$10.66 US$14.24

Q: meu amplificador derreteu os indutores de saída após 3 meses de uso, uso uma fonte chaveada que fornece um pouco mais de 23 volts, tentei refazer o enrolamento, mas continua aquecendo muito, o que pode haver de errado? há um email de contato? gostaria de comprar outro do mesmo modelo mas tenho medo de acontecer isso novamente.
