The PSU that came with my Thunderbolt was DOA as well, like yours there 
was the characteristic smell of burnt electronics when I opened it up.

I was lucky, I managed to get an almost exact replacement at a local 
electronics shop and, having looked at my dead PSU, I would suggest that 
repairing the dead one might be a bit of a problem.  Even if you work 
out the resistor value you have to wonder what caused that amount of 
current to flow though it?  My guess would be that something else went 
short circuit and replacing whatever it was might be more trouble than 
buying a new PSU...
