Yes, 1-5. that is your transformer power in, 7 and 12 are grounds, 6, 9-11, 13-15 are your various receiver loads. I have used one of these designs in my own 1010, took a bi for readings to get proper, but once they did, this board helped me to create a monster of an Sx-1010. I do think it helped smooth out the power, resulting in a more efficient unit that can deliver more power safely, but also keeps it cooler. I do note mien takes a bit longer to warm up than the other 1010s with standard boards. Sort of makes sense, given the modern layout and the fact that the footprint is shorter in height over the original allowing for more airflow. I'd call that a win in my book.
