   I don't see that as being an issue, though (the re-fusing bit) since   
   whatever has gone low-resistance is clearly drawing current away from   
   the other healthy components, no? And if said component has gone   
   low-res (as we assume it must) then cooking it a bit more doesn't   
   matter in the least since it's going to have to be replaced anyway.   
   The important thing is not to do it to such an extent that the PCB   
   becomes heat-damaged - in my submission anyway.   
      
   I'll check out the caps you suggested, however. Sounds like a good   
   call.   
   Thanks,
