Default Inductor sparks along with bass?

Alright, so I'm trying to fix a MTX jackhammer jh600 that broke down on me.

I found a bad output mosfet and ended up replacing all of em' and a few other parts. Now it works, but barely. The output seems pretty quiet for what it is, and after about 10 seconds the inductor starts sparking along with the bass and overheats shortly thereafter. From the look of it, it was doing it before it cooked itself.

Does anyone know what the hell could cause that?

Check magnet wire insulation, an intermittent short may be happening between adjacent wires or between the wire and the PCB.

Also, check that the inductor is not opening intermittently and that it's soldered to the PCB properly.
