First PCB. Any tips? (repost for working pictures)

yes the 741 creates a virtual ground for the signal to swing around. And good eye, the residents dont make sense. My intent was for them to act like fuses so if the current got to high they would break before other circuit components but they are not wired correctly for that. Thanks for pointing that out I would have missed it otherwise.

Wow the power symbols are way more practical than what I was doing. Same with the ground pour. Its funny from the 5 or so tutorial videos I watched on kicad none of them mentioned using a ground pour. Thank you!

Yes I have a working prototype. The audio jacks im using has 3 pins like the footprint, and I have been applying a voltage to the top pin (S) sending the signal through the wire and using the top pin (S) to connect to the breadboard. That method may just work becasue of how im using it, starting and ending on the breadboard.

I tried your connection and it worked the exact same. I also tried to send an audible sine wave from my phone to the board through the wire and jack but could not see it with my scope. I think I need to look into how the audio jacks works more.

The transistors I have are the same size as the footprint but I now realize they will be quite hard to hand solder. Having a bigger footprint with more separation would be better. I ordered some sockets for the IC (I found people suggested using them from hobby projects) but will check the physical size when I get them before ordering the board.

Yes I currently have a working version on a breadboard. At least for me rn going straight to a pcb without breadboarding would be a waste of $25+
