Hi All, I've seen this behaviour with others who had trouble with this circuit on the forums, but unfortunately no solution:
I've built a Quad Slope for eurorack, and it's not entirely disfunctional, but the LEDs are always on, and self-oscillation does not work for either of the four parts. The trimmers don't do anything to solve this behaviour :S Anybody have an idea? And yes, the trannies are in backwards all the way across both boards.
Second problem which I don't understand is that one of the bipolar outs shorts the entire modular, even making the power supply turn off entirely (luckily it's a protected supply).
