It appears as though Midwest-Analog along with Thomas Henry is nowhere to be found on the internet nowadays with the exception of the wayback machine site. A real shame this is because they had some very interesting synth construction books and tips. I got my Electronic Music: The reprints copy a couple of years ago now, and glad that I did, just wish I would’ve ordered the other books as well. Feel free to rummage through the wayback machine site and pick what you want, some schematics and all the text still left.
