The sub channel on this amp is drawing excessive current.With R534 out of the circuit the 4 channels idles fine and play good audio.Amp came in with the trace from R534 to Q506 burnt.When i repaired the trace it started to draw to much current.Q506 and the driver transistor it connect to tested ok.The outputs for the sub channel does not heat up during the current draw.
