Velleman amp problem, help needed!

[geowal19]

Right I got THIS amp and soldered it and it was all working good so i was listening to music on it for a while to really test it then all of a sudden the music cut out then I just got wot sounded like ineterference amplified a lot. The power resistors started to get very hot and started smoking a little. Do you think if I just replaced them it would fix it? Or would there be a cause to why this is hapening to the resistors?

Thanks

Probably the Output transistor becomes leaky or faulty or you might have a bias problem.Test the output transistor and check
that small blue pot and other parts connected to it or just check all the semicon, theres only a few so it would not take a long
time to check them all.
