First, thanks for bringing this to everyone's attention here. Awesome info.
I'm about as mechanically/electrically inept as one can be, so pls pardon the ignorant/basic questions. I am dying to try this thing out.
What is an "L" DC power plug? Any links to a picture of one so I can understand?
Using the photo of the Pyramid power supply, were you saying that you take the bare wire & connect it to the red/black terminals, and the other end of those wires are soldered to this "L" plug? And the plug then fits into the amp?
