Hi.
I need help building a BJT circuit with only discrete components. I have come up with a common circuit and I don't know if it would work. Attached to this post is the circuit in LTspice XVII. Here is the specification of the project;

1)Supply voltage: >+-15V
2)Input signal voltage: 100mVp - 1Vp
3)Gain: > 20dB
4)Load Impedance: 8ohms speaker

As can be seen in the circuit, there are 3 parts to the circuit. a differential stage, gain stage, and push-pull stage. I need to know how to calculate the values of the push-pull stage.

I hope you all could provide guides for me. Thank you.

 

There was here a discussion about it. Serach for it.
