The fader element looks
great!
Okay, no sweat on that broken wire. Man if you were close I'd jaunt over and fix it up, but you're not soooo...
The same things in my soldering tips thread work here too. That lug has a hole in it for the wire and you can heat it up and suck the junk out of it, trim the end of the wire just to get a clean end, strip a little off and solder it back in.
Let me know if I can help but I've had this happen several times so, again, it happens.
Not that it isn't a bummer, but totally fixable.
