Yes.R9 has 4.5v - 1.6v. am assuming the 1.6v is the drop across the resistor?
Yes again.same goes for R2
It is correct. The inverter transistor T7 is turned on so it turns off the entire right side of the H-bridge. The entire left side of the H-bridge is turned on and draws current. When the input signal goes low then the inverter turns off, the entire right side of the H-bridge turns on and the entire left side turns off.current draw is not what I expected on T7 to T! = -2.38pa
