I have all the stuff to do that ad-20 mod, but I was going to run the power from the main power and use my Makita battery to power it. But then I changed my mind and decided to pick up a ps-2, samson adaptors and those mini xlr connectors to do my own phantom mod. I haven't jumped in yet because I'm still waiting on the adaptors. I'm also going to build a mini xlr to mini for using the BB when I want to have as little stuff as possible.
