Really happy to report that this works! I used Willard's most recent layout incorporating the mod board. I was pretty nervous, considering the size of the layout and the problems people seemed to be having. For the questionable part, I used the 22R resistor from the original layout. It does get hot, as does the 7805. Also, looking at the original madbean PDF, is he using the 78L05, or does the 7805 also come in a TO-92 package (judging from the picture he included at the end)?
