I see. Yeah, using SPICE instead of GNU-Cap gives exactly the results I expected. The output plots right over the input. I think I'll just go with SPICE for now. Since I'm not an EE I'm just trying to validate the circuit before I build it. Regarding Steven's comment, I did not intend for that RC to be a high pass filter. I thought 1/(2 * 3.14 * 1000000 * 0.0000001) = 1.59 Hz?
