I've been looking at trying to incorporate the slam mod used on the echo base to give me that fat self oscillation on my sea urchin at the touch of a momentary contact switch, but so far all of my attempts have come up short. The echo base uses a 20K resistor above the feedback pot that they put the switch across for the mod, but that isn't on the sea urchin schematic. Any idea how I would incorporate thid mod into my urchin?
