    i know that the circuit attached to this thread is a differential limiting amplifier , and the collector of Q2 acts as a current source , but other than that , i can't get my mind around it !! P1 is the input , P5 is the output , and Vcc is +12 connected to the 27 R .

    could someone please walk me step by step on how to analyze (understand) this freakin Amp !!
