An update to my posts about my faulty BB from Church Audio - got all the parts in and made my own. I tried my best to keep it basically looking as close to Church's design as possible, which I think worked out pretty well - found a decent amount of the exact same parts on mouser. Now, I'm not sure what internal components and layout Church uses, so I just built mine off of the instructions from
https://forums.sonyinsider.com/topic/14343-how-to-build-a-stereo-microphone-and-battery-box/The components were:
2 x 4.7kOhm 1% 1/4W Metal Film Resistor (MFR-25FTF52-4K7) - Matched to 4.70kOhm each
2 x 25VDC 10uF SU Bi-polar Capacitor (ECE-A1EN100U)
1 x 9 volt battery connector (Keystone 84-6)
Approx. 7" 3 conductor shielded audio cable
1 x 3.5mm stereo jack (NYS231LBG)
(plus solder, extra wire, electrical tape, and some hot glue)
I also wrapped everything with 1 layer of electrical tape before using hot glue to give the BB structure, then used another layer of tape on top of that. I did this so that the BB still has structure/protection, but should also be repairable since there isn't hot glue between every component. The only components which are directly hot glued are the two battery connector cables and the bottom of the output cable (just tiny amounts to keep them in place while I was doing the first layer of tape.
I put my BB next to the faulty UBB in the second attached picture for comparison - mine has the thicker cable!
I'm pretty happy with how it turned out - the biggest difference between the one I built and the real UBB that Church sent me is that mine works
