    Hi I have an Amp which I simulate with BJT's. I am attaching the schematic
    also. The transient analysis is failling due to the so called
    "ERROR: TR1: Jacobian singular at t = 0.000e+000, aborting transient
    analysis". Can you help me find what is causing this behaviour? Is it a
    bug?

      Can you post the netlist so we can look at it?  I am not sure what that is...
