Gary7ross7 Posted May 20, 2019 Share Posted May 20, 2019 Hi all My amplifi 75 has no sound through the main 8" speaker. I have opened the back and noticed a 5 pin chip has burned out on a pcb. Does anyone know what chip that is? I can't find any detail for it anywhere. The chip itself has UTC TDA 20 printed on it, but I can't see the rest of the wording as it's burnt. I wonder if any of you delightfull chaps could help. Thanks in advance. 1 Quote Link to comment Share on other sites More sharing options...
