So I have an A-100G3 subrack inside a 6u road case and I want to add another 3u of modules. I'm either going to make my own setup or possible get a Tiptop Happy Ending kit. The Tiptop setup has a 110v wallwart to plug into the wall, which I hate. Is there any way to tap power directly from the Doepfer A-100G3 busboard/power supply
