Im new to Sziklai pairs and could not find any information on how to do calculations for this case. Im trying to do DC calculations and the info i have : +IN and -IN are for AC source, the +VE and -VE are 15V. I want to know the currents of both pnp and npn transistors emitters, bases and collectors but since I need the base currents known (which i dont) to calculate the collector currents, I'm stuck.
Additional question:Are the resistors R3 and R4 meant as a voltage divider to make sure the voltage difference between emitter and base of Q2 is 0.7V? Or is R3 a feedback for the Sziklai pair in which case I'm not sure what R4 is for?

I would appreciate any help with the calculations and explanations.
