[sdiy] Monotron Schematic

[Steve Carter]

Yes thanks Sam.  Interesting circuit. I hadn't come across the IMX9 dual transistor before. It maybe a small box but SMD has allowed them not to scrimp on design. I now understand how they do the modulation sync by using an LFO reset line - couldn't figure that out by just staring at the board - it just wasn't talking to me.
