A short in the B+ line shouldn't cause that cap to overheat. A short would drag the voltage down and so put less stress on the cap. What COULD cause it to heat immediately like that would be if one side of the transformer HT winding were shorted to ground. As said before, whether your error or an error in manufacturing, the cap polarity may be reversed (I've done this trick before while swearing I installed it correctly. More recently, I pulled a pair of 10 mF/160 V caps and installed them into a radio with a 265V B+ line... )
At any rate, I would pull the rectifier tube and check your transformer HT voltages to the chassis. Also check the resistor (47), as if there is a transformer short, it would likely be open.
