That's the purpose of this forum. But, since we're not clairvoyant, how can we help you if you don't post a circuit diagram and state what the problem is?

thankxxx for responce.infect my problem is this i cant find same volt at input stage transistors..i tried to make many time many circuits but almost the problems is same ..volts are not same on colloctor of input stage transistors..and one more important thing..why i apply the ground in circuit.volts show unblance at colloctor.and when i disconnected the groung from circuit ..volt are same ..i dont understand whats my faultt.i really dead tired due to this fault..and feeling hopeless..i follow same to same diagrame instrustions.but dont know where is the fault,,i m a new user here don,t know how to send u diagrame .if u have any potel address i will send u diagrame or pics with all details.. thankxxxx
volt are not same on emeter .one side have -0.5 and one side hqave 0.9 volt..also volt on base input and feedback also 4.5v inpuut and 3.5 volt feedback..volt are not same also on base Q651.Q653 and the same Q657 and Q659. i just make input stage but deu to this problem.every time i left the circuit in this stage..can u help me..

Could you please ask your questions more clearly, and in full words/sentences? Text speak is not allowed here as it is often difficult to read and to understand. I expect you will get better answers if you make your questions clearer and ask them in English. If you must use a translator, feel free to do so.
