Not sure I understand how this circuit operates. The voltage divider is creating a negative voltage at the base of Q3 (-6.75 v), which from what I've been taught would not forward bias the transistor (+0.7 v ?), and thus there would be no current in the middle leg.
The circuit does work, I was able to use the pot to balance the node between Q1 and Q2, and the circuit put out a 8.5 v (pp) signal before clipping.
what am I missing?
thanks as always!
