Wow, this is really good. I didn't know it was possible to create an opamp with only 4 transistors. I changed the configuration to an inverting amplifier, and it worked great. Good job 👍

Hey, did you modify it since my last comment? That's OK, but would you mind publishing the original 4 transistor version again? I was going to try to build it in real life.

Here you go. Just know this last circuit improves the original greatly.
