Help to understanding a circuit

[mydsp]

I am reading a schematic and can not understand the purpose of this circuit.

I think Q9-Q11 maybe the transistor, Anyboby can explain the purpose of this circuit?

Q9-Q11 are transistors. The purpose of the circuit is to test out "ESP".

Please attach a schematic.

what does ESP mean?View attachment 65339

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.

Actually, I am not sure that Q9-Q11 are transistors, I just guess from the name. Can you tell what these Q9-Q11 are from this schematic?

 

[ronsimpson]

Probably transistors.
