See above messages about testing without a load & DC offset voltage:
Check the diode string CR20-23. You might also try pulling the IC (U12/13) out of the circuit to see if it is causing an offset or current draw through the power transistors. Also check current limiters Q6 and Q7 for shorts or damaged junctions, and diodes CR32/33 (CR48/49). I don’t think increasing resistor values is the answer to you problem.
