I removed my power switch when i was inside the case to do the digi-mod. As for protecting the Phantom button it would be hard to put a box around it (like on a power strip) but w/ some CA glue and clear plastic (i'm thinkin peices a RJ45 jack after a vice grip attack) you could do some thing like this. XLR is the Right XLR input, VOL is the Right Volume knob, PH is the phantom button. Looks like i got a project for tonight. I'll snap a few pics.
