[QUOTE="akheathen, post: 7173308, member: 629234"] ....... something just doesn't add up......... you put power to the negative speaker output, and it fried 4 fets...... it sounds more to me like you blew a channel. either way, you need to map the circuit, and replace the resistors, diodes, preamp transistor, etc..... and make sure it's ballanced with the other side. when you go online to get the new fets, mouser can cross it over, and you can match it to something bigger than a to-220, and you can get better heat transfer. it appears you have plenty of room, but a mount tab might not clear on top [/QUOTE]
