    Hello,

    What class amplifier is this? I have been experimenting with multisim and now confused on what class amplifier I just built.

    Could you also please explain why?

    I am also open to any improvement ideas as well. The output voltage you see is before distortion. and the input is just 1kHz sine wave (simulating and ipod)....:)

    PS...I used an old concept circuit/drawing from forum member "SGTWookie" from a few months ago!

    I always use white colored dots. ......... They are all but invisible.

    That's true, .... until someone quotes you. ;)

    Good idea none-the-less!

    Did you mean to wire R5 like that? SOP would have the output of the generator connected to the high side of the Pot and the wiper connected to C1 input.

    Thanks everyone!!

    just wondering if you could give a quick summary of why.

    I am re-posting the circuit but under a different question. I would like some advice or guidance on how R1, R2, and R4 are selected/Calculated and purpose.
