BTW I do not quite understand the schematic.

What is B+? If it is a rail, how does the driver drive anything? Let alone the fact this same signal comes to bases of Q5 and Q6 and creates different voltages.

Oh, I got it.

Ron, I think you drew the bases going to the wrong places - they should go to Q1 and Q2 collectors respectively. And you have them at B+.
The voltages at the bases and collectors confirm that.
