Can someone help me identify the biasing and operation of these amplifier circuits? We went from basics voltage divider, base or emitter bias and feedback to this on a lab. It looks like a voltage divider bias with common emitter using a Zener to set the bias. I’m not sure why R5 and R2 is in parallel could have just used a 470...
This looks like a CE Q2 controlling a emitter follower Q1... please confirm
