The more helpful idea would be to suggest an exhaustive look into where is the overload taking place? You can go so far as to seperate stages, but this might not give a clear picture if there is stage-stage interaction in the PS.

If you it is an open loop, or short loop NFB amp you ought to be able to proceed from the input stage to the final and see some evidence of overlaod/clipping. Be thorough, and ask questions as required.
