Sansui A 910 Integrated Amplifier (stuck in PROTECTION mode)

Stuck in protection mode. (The speaker relay does NOT click on) I checked voltages at the output transistors. The right side voltages looked good, but the left side voltages were bad ( that's why the relay doesn't click on)

I found a bad 45580 op-amp chips (seen in picture above)  location on the board (IC2) Replaced Chip and unit is working great now. Very nice sounding amplifier!
