So i've gone ahead and ordered a switchcraft jack. Also ordered some straplocks for it while I was at it...I'll post an update once I get all that taken care of. In the mean time i've sorta hot-wired it so that the active preamp stays on (this prevents the crackling so i'm guessing the old jack failed somewhere with the switching mechanism for the preamp) and I've just been unplugging the battery...it's a pain but at least I can use it without extremely annoying crackling all the time.
