That is a old fashioned style of heat sinked wire wound resistor commonly referred to as a "Candohm". If it was smoking then something connected to it was drawing a lot of current. If not then the only way it would do that on it's own is if the insulation broke down and the resistor shorted to ground. Did you power the set up before you started working on it? I'm guessing that a mistake in the wiring may have caused this, such as something connected to the wrong point, or a filter cap connected in backward.
