ASTRO HT Battery Eliminator RTL-4224, component ID

I have a ASTRO HT battery eliminator, model #RTL-4224.

It has a specific warning on it, 10v MAX. Well, I hooked it up to my variable voltage power supply that was set at 12v and I forgot to turn the power down. You can probably guess what happened next. I let out the magic smoke.

After opening it up and inspecting it, it appears that one of the components (inductor?) was completely toast, so I removed it.

Pictures:

Top (removed component spot in red box.): https://i.imgsafe.org/03fbaa9c66.jpg

Bottom: https://i.imgsafe.org/03e3b397d5.jpg

SO, my question is, what is that electronic component, and what exactly should I buy to replace it with??

Thanks!

OK, after thinking about it, that is a wire-wound resistor.

Now I just need to find out what value it is.
