Eva You are making too much assumptions too quickly. How do you know that only a single MOSFET is blown, and how do you know which one is blown?. When one MOSFET fails it usually becomes shorted and causes maybe a dozen parts to blow. Also, TO-274 is not the name of any known popular package, do you mean TO-247? What is the part number or whatever is written in the transistor case? Does it contain any logo? (also useful to identify manufacturer). TechnoTools yes the package is 247...;) the component is damaged... there are 4 mosfet.. two are NPN and two are PNP (i believe...:)). one of these MOS is damaged.... the only logo that i can see on it is a great F. its impossible read other informations becouse the component is damaged i can read the other similar mos. i not believe thet F is firechild becouse i have already researched the component in the web site.... can you tell me where i can buy it? thanks and excuse me for my english. it s not perfect. Markus2006 Have you tried asking your questions on Rockford support forum? http://www.rockfordfosgate.com/forum/ It seems that you don't know much about MOSFETs and amps and repairing it on your own can be quite a challange. Marek TechnoTools rockford says that is not possible buy spare parts.... is it possible? tomorrow i ll read the number of Mos in another amplifier t20001. PS. my amplifier now is working but i want change the damaged component before is too late.... for this reason i'm sure that the component is the only damaged on the mainboard.. with the tester i have measured it and the other similar on the mainboard. the two mos are equal. the other two Mos have different values
