calentamiento amplificador

Mi amplificador PA-8 CRATE funciona solo unos minutos, se calienta el disipador en exceso y luego deja de amplificar.	kuzkindom

Eso que se apaga seguramente es por proteccion, antes que se queme.Primero que nada comenta con que parlante lo trabajas, si le agraste mas parlantes, revisa bien las conexiones,despues fijate algo, vos prendes el ampli de 0 se te apaga en x tiempo, siempre es el mismo tiempo? si lo dejas prendido pero no le inyectas audio se calienta tambien? Puede llegar a ser la salida defectuosa, como poca refrigeracion simplemente (agregando unos cooler se soluciona) puede ser que se este pasando en tension (tendrias que ver de conseguir el diagrama y medir o ver la salida los trans o CI y buscar la info)	cristiancoro

Hi The problem is with the amplifier itself. Crackling is usually capacitor related and you will need to have the amp checked over to properly identify the cause. Some amps are also prone to pick up static from other electrical items which can also cause these problems. I had a crackling issue with an old Crate amp of mine which turned out it was due to being too near a computer/monitor so it is worth eliminating these things as a possible cause before having i have a crate mx15r amp and the component on the pc board labled ic#3, its the one thats mounted to the heat sink blew out. problem is its burned up so bad that i cant read the i.d. numbers on it to replace it. there are 5 pins on it and all are soldered to the board. any help would be oh so sweet. Problem for Crate FlexWave FW15 Guitar Amp Combo, 15 Watt Single 8... I have a crate PA 8 and it makes a crackling noise http://mx.mouser.com/Search/Refine.aspx?Keyword=tda2050 http://www.crateamps.com/products/findex.php?catID=1	el satanas de estados uni
