That thing must have a ton of capacitance which I think may be hiding underneath. If you did send it in for repair, re-capping would be a good thing as Steve suggested.

I could be wrong but I think the way the ADAs are designed, you just change out the power supply instead of having to get into de-soldering and soldering. If it really is like that, it would be very righteous!
