Well, more of an acquaintance you keep in the back of your mind for time when, if you have a problem... if no one else can help... and if you can find them... maybe you can hire...RS/CPC-Farnell/McMaster-Carr/SJSC
For everything else, there's Amazon or eBay
Why not replace it with errrr..... some heat shrink?
RS Components is your friend.
