AT-12 crossover question

A good while ago, I went from "Lets fix my AT-12s cabinet rattle" to "Could I build these from scratch?" as one does. I've been aiming for as close to manufacturing as I can get but while documenting the cross fades, I noticed two things.
- I can't figure out what rating the "MCI" PTC resettable fuse breaker thingy is
- I also can't seem to find any 16ohm 5Watt potentiometer replacements (although that's not the main priority for me)

As of right now, I have an 8 ohm dayton audio resistor keeping the middle position for the potentiometers since I can't find em' and in my updated cross fade network I just neglect the PTC but I don't reallyyyy want to do that in the end. Any help is of course very much apreciated! Step by step, I will have more AT-12s :)

I meannn if you are implying the fact that audio karma loves the AT-12 series and a convo/conversation* is coming, I'm always down lol ive been documenting literally everything I could, I even studied japanese wood joinery to try to fix the cabinet rattle being my first problem to begin with!

welcome to A.K.
 
I don't know much about building them, but I have a set of AT-12 myself and I love them! One of the best, most efficient and well rounded speakers I have ever owned! I can play anything from classical to hip-hop without missing a beat!
