A ten-step sequencer kit behind a Buchla panel

An old Buchla SCR lighting control panel, recycled into an analog 10-step sequencer. The bare circuit board is sold by Music From Outer Space. I bought the parts, soldered it up, and assembled this. It works! I'll post a YouTube video of it in action soon.
