Hi...Made the first circuit yesterday : gain was about 300..If you look at 2nd image, channel 2 is the input and it says 20.88 mv but from the function generator it is 5mv..what's wrong?? probe is 1X...Read a post that says it's best to use 2 resistors in series at emitter then bypass one so will change
Also wanted to connect output to emitter followers (3rd image : I did not make the circuit )..like 4 emitter followers connected together so the leftmost follower has input impedance >60k (output impedance of first image is 6k)...Will this work? (I dunno : beginner here)...lol, I will not use 2n3904
Thanks Jony https://forum.allaboutcircuits.com/...-with-class-ab-amplifier.158961/#post-1388410
Reading push-pull, bootstrap and negative feedback today : hopefully slightly better design tomorrow : want to hear a voice from microphone to speaker with transistors
Also, think i've seen some audio transistor amplifiers and the input is inverted only once! why not twice to get the input back again?? it does not matter?
Thank you
