    Hi all,

    Hoping I can get some help with the attached circuit. The circuit is an NPN transistor leading into a Darlington transistor, output of the circuit is a standard speaker with an impedance of 8ohms. I am struggling to analyse the circuit to calculate the AC gain, could I get some advice?

    I have purposely removed numbers as I don't want it answering I am seeking advice to allow me to complete the analysis by myself.

    (Hfe of all transistors for example is 50)

    Thank you all.
