I think he was pointing out that the only way to answer questions when you don't post a circuit is to use extra sensory perception.... or maybe a crystal ball.
Of course, having seen the "schematic", we aren't much farther along.
You gave us part of a 'schematic'. The parts are not labeled. No values. Transistors have three legs, E, C, B which is which. Transistors could be NPN or PNP or N or P or maybe Junction...??? There is almost no information. My crystal ball is in the shop for repairs.
