RF T4000.1 burnt resistor?

A week or two ago my amp started cutting out to the point where it went into protect mode, and made a terrible high pitched screeching noise.. smelt like burning plastic.. Is anyone familiar with what all these resistors going around the amp is for? and maybe why this happened?

MOSFET looks cooked.

The burnt spot is now cleaned up with some rubbing alcohol.. and it looks like it came from the grey long thing..resistor? and as you can see there are little orange things on the right hand side of them.. i think the orange thing was bent over and touching it.. maybe that was the cause?

the yellow things are tantalum capacitors.

Kind of looks to me either the MOSFET, resistor, or capacitor is cooked.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

so if i replace all 3 of those the amp should work again? and where would i even get ones to match?
