This video is a very quick guide to using Falstad to simulate audio electronic circuits. It features the Linear Power Booster circuit which is more widely known as a Common Emitter Amplifier. We'll revisit this circuit in future videos, add an AC ground capacitor and analyse it in more depth.
Falstad can be found here, it's free to use:

I am no expert in electronics, I remain a curious hobbyist. However, I have always been fascinated in learning how audio electronics works. Disassembling various radios as a kid and eventually becoming interested in designing and building guitar effects pedals. I attempt to understand how these systems operate electronically, and due to this approach, I have picked up a few bits of theory along the way. If you're unsure about it, my best advice is just get started, mistakes and corrections (and the occasionally popped component) is how we learn. You win or you learn
If you found this useful, want to correct my knowledge or would like to know more about my DIY pedals and test gear, leave a comment below.
