Thank you for the clarification 8)
As I was saying previously, for now we forget about the transistors. Since R2 is disconnected from pin11, the transistors cannot get any signal from CD4093, so now the voltage across OUT+ and OUT- cannot be influenced by the potentiometer, thus it is not important.
So the LED light gets brighter or dimmer according to the rotation of the potentiometer, which is good. Does it behave like the LED's of the locomotive that I showed in the video? If YES, then we can be sure that CD4093 works properly and we can concentrate on the transistors.
