EDITED: I think you need a brief test at full power, to check voltage drop at R 146. Something is wrong at Q114 base. It could be shorted or those -34V coming from somewhere. Please check Q114 or replace it before doing a full power test. Q112, even if not perfectly symm to Q111, has -19V at the emitter and Q111 has 17.8, I don't see a short there. You could also check in this same condition (with DBT), the good channel at that same Resistor and Q114 equivalent.
