Narrative:

We were running triple simultaneous ILS approaches to dfw. One of my aircraft got a stuck mic. I tried several times to see if any of the other aircraft could hear me but was unsuccessful. I had several aircraft leave my airspace because I was unable to communicate with them and turn them. I made the necessary point-outs. Every facility I've ever been to had access to emergency frequencies at all positions. Not here for some reason. They have one position with 121.5 available and it is on the other side of the TRACON from where I was working. Had it been available or within a reasonable distance; there would have been much less of a disruption from one aircraft tying up my frequency. We also have ancient (seriously) interfaces instead of etvs or something similar. It really is embarrassing and it has already been identified as a safety risk but I don't know if/when they are going to replace our current system.
