Hi, an amp of mine has stopped working. A carlsbro marin 8400

I have found a ceramic resistor looks blown and the multimeter confirms this

The resistor is a rx27 5w 2k

2 questions,

1) I can't find the correct resistor, would a 2k2 be ok?
2) are other components likely to be blown as well, or is a single fault like this common?

Any help greatly appreciated,

Many thanks, 

Ben
