    Class AB Power Amplifier Design

    Hello there and thanks for your response. That circuit diagram is an example that I used from another website and where it shows 0V on that diagram, -15V is connected there instead on my actual circuit. The speaker however is grounded, should it be referenced to -15V? Thanks in advance.
