    I have project which talks about differential amplifier and I did design it using (bjt Amplifier ,which is Q2N2222A Transistor),but I have problem ,output Voltage should give output (+ - 7.5 V peak to peak using Differential Mode) according to my design which is attached with this topic,but I don't know how can I make (Differential Mode,or Common mode ,or Ac analysis by pspice) for my design to work properly,I wish you can help me as quick as possible ,because it's submission will be on Tuesday,and 10 marks for project,

    There is an option in PSpice for AC analysis like the transient analysis.

    In your simulation on the 15V line is shows that it is 0V. Why?
