Like everyone else I'm sure, I am amassing this collection of warts on my wall/floor/etc. Any reason I can't get/make a 9V 3A supply and just wire everything to it? (9V because almost everything I have is 9V) Is this a Bad Idea? Thanks, Irish BTW, I got my Midi Thru box done - worked first pass (almost; had a bunk chip but not my fault).
