Hi CircuitLab community,

I am getting very frustrated with a circuit I am working on. I built a sine wave oscillator in the lab that results in sine and cosine wave outputs (90 deg phase shift). I have modeled the circuit that I created in CL using the same schematic that I built it with. Initially, it was working and in transient analysis I was seeing the expected sine and cosine outputs. Now, for some reason it has stopped working and I am only getting DC output. I really really wish I saved the graph when it was working because now I have spent hours troubleshooting this and I am looking to anyone for help at this point.

Here's the link to the circuit:

If anyone has any ideas as to why this is only giving me DC output and not oscillating anymore, please let me know I would really appreciate it.

Thanks so much.

Wow! Knew it was something simple.... My time div was off....
