Clean up everything with a toothbrush and solvent (acetone, alcohol...) and make sure that there are no shorts.
If the problem remains, remove the drivers that directly drive the outputs. Does the problem remain? If not, check the drivers (out of the circuit) for leakage, shorts and open junctions. If they are OK, reinstall them and do the same thing for the next stage back.
I'm assuming that you've confirmed that there is no excessive DC from the preamp section that's causing the offset.
