This is the last of the practice amp pcb. Even before firing up LT spice, I knew the filter after IC2a seemed familiar. It's a notch filter similar to the one in the Condor circuit I posted about before. IC2b is just another amplifier. I guess it keeps the impedance low for the power amplifier?
I played around with the power supply in LTspice and it seems that changing stuff alters the response of the circuit. I didn't know that could happen. I thought the power supply was just for powering stuff and forgetting it exists.
