Default Does Anyone Know What This Is?

I've isolated a problem on my amp circuit board. Can anyone tell me what the gray cylindrical object with the burn marks under would be referred to and if you know where I can get one. I tried googling the numbers I could read on it but nothing came up. Thanks for your help.

resistor 10W with a accuracy of 10%
Can't see the resistor value in the photograph.
Should be able to see on the other side of the resistor.

Resistor value should look something like this:

0.5R which would mean 0.5 Ohm value or like this
1R which would mean 1 Ohm value etc.

And what no one else has mentioned, that power resistors generally only burn up when something else is wrong - given that the original poster could not even identify that this is a power resistor I recommend he find a qualified service technician to fix it. Given the presence of 350V electrolytics in close proximity high voltages are undoubtedly involved. Repairing this device whatever it may be is not a job for a newbie.

Hopefully the OP knows about things like safely measuring high voltages, and discharging electrolytic capacitors, in addition to other safe trouble shooting techniques, otherwise he should not be poking around in there, definite hazards exist.
