i will not slag you off, you were right with these amps blowing up! the first time, the wiring was going the wring way and it frazzled the track on the board. the second time, a resistor (nearly 2 got taken out) went on fire, rendering the board as scrap (nearly!). the speaker that was coupled made a buzzing sound (had it on for no more than one second) and then tried to make a burning smell, i ended up with 25v ground running through it, no wonder it tried to go on fire. maybe i should have listened to you before applying power?!?! at least i've now learned to go to the shops and buy an approved amp!
