I have a question, does anyone here know how to make a LM741 audio amplifier? That is, 4 or 8 ohms, with the values? Ive tryed searching stuff up but i can't find anything. Or maby a Mosfet amplifier?

Also I am wondering how to make a lowpass circuit. I know it can be achived with a Capacitor and a Resistior. But I want an amplified LP circuit. I really need help. :o
