I'm trying to sim the input circuit of an audio EQ, but I'm getting only DC at the output.
This is what I'm trying to simulate:
It's the input section of this schematic:
Here's what I've created, the .ASC is attached:
I'm using an LT1057 model as it is described as a drop-in replacement for the TL072, and I'm assuming it's enough to get me in the same ballpark for what I'm trying to achieve. I've successfully simmed tube circuits but this is my first go with an opamp. What am I missing? I've tried searching for an explanation of this type of circuit but I haven't been able to find one. Please be gentle on me as we pop my cherry.
