Hi,

I've been trying to get into discrete amplifiers. I know the electronics and I can derive the output as function of inputs etc. But it's only doable on smaller sections of amplifiers so, I suppose working on an amplifier requires a perspective, being able to see all the blocks at first sight. Right know I'm looking into somewhat complex designs and try to separate them into smaller building blocks in my mind. Here's Mr. Elliotts P27 power amp, I built it in LTSpice and played with simulation. Can someone help me understand this circuit? I have a couple of guesses but would like to hear from you instead.

Thanks in advance

Edit: I currently am reading the book published here, teemuk's, but working on something real is always more rewarding in my experience.
