 I don't know what it is, but I have a suggestion. Write the model number
 down and find a Sam's Photofact for it. If it's an old amp, you may be
 able to find the Photofact in the library. This will help you identify
 the component, may help you identify why it failed (if it did). I have
 to say that the chances of resurrecting a dead amp by replacing one
 component that "looks smoky" are not great. Sometimes it works, more
 often not. If you find the part you are looking for, consider the very
 real possibility that the replacement will burn out also, it may have
 failed as a result of another problem.

 I couple of wild guesses: 1-shorted speaker output, 2-leaky electrolytic cap.

You're welcome, I hope it's some help.
