Hi, What kind of simulation that do you want? What is the error?

Also I'm not sure if the circuit is wired correctly. Please teach. Click to expand... The first problem is actually caused by the second. Due to wrong wiring, the node "output" is deleted during simulation. Use "View SPICE Error log" (Hotkey CTRL-L) to find the errors, try to fix them one by one. Hint: There's no potentiometer symbol in the LTSpice library. R1 ande R3 are just resistors with an unconnected wire next to it. Also power supply V1 is halfway unconnected and has wrong polarity.

Click to expand... Take a look at Falstad's interactive animated simulator. Free to download and use at: www.falstad.com/circuit It's great for simple circuits. Doesn't hit you with a long learning curve. The potentiometers are interactive. You can see the effects immediately. Mosfets are quirky. Expect to apply high bias voltage. Reduce the time step if you want 1.8 MHz operation (shown in the diyaudioprojects schematic). To simulate an audio signal, combine a few sinewave generators in series, at different frequencies.
