Thankyou so much .... I'm a noob trying to get his head around flow and VIR in schematics, so this was very helpful. Looking forward to more of the same .😁
I came across this video pretty much the day after I had used Falstad for the the first time and learned a lot! Those scopes are amazingly useful. I want to build a headphone amplifier so this video was extremely topical. I had reduced the voltage to 5V (as I want to power mine over USB ultimately) and your specific circuit was all wonky with that DC voltage. Adding a slider for each resistor seems like a perfect way to tweak the values such that the resulting amplified sine wave is optimal and doesn't clip. Can't wait for those follow-up videos!
Thanks. That sounds like an excellent project. This circuit would be considered a preamp rather than a power amp, like in a headphone amp. If you wanted to build a discrete (Transistor based) headphone amp I’d suggest a class AB design (the video one is class A so really inefficient). If you want a super efficient 5v powered headphone amp, check out Analog Devices MAX IC’s they’re Class D so super efficient and will run on lower voltages. 👍

Thank you, very intuitive and clear explanation!!

great lesson, well done!
