Good job on overloading the P/S. That's exactly what happens...at first, but then, you stopped before the REAL damage could get going...hopefully. The hot smell might indicate that you've damaged the wallwart, however.
If you have something that has a SPECIFIC case with a SPECIFIC power source for it, use that for that ONLY. I don't think Moog intended for that sort of usage, nor did 4ms. Unless you know what you're doing with current loading, specific voltages, and you have a serious DC supply instead of a wallwart, don't try anything like this again.
