In the simulation, it runs like it should, clipped lows are at zero, and highs hit at around 5v+. But in real life, the output does not stay 0-5v and instead sinks down and goes from negative 2.5v for the lows to positive 2.5v for the peaks. What the hell is making it drop into negative territory?
Negative compared to what? Is there a missing ground connection somewhere, or some source of capacitance?
