The emitter of the A56 drives the muting transistors. There's likely one series resistor. Make sure it's not out of tolerance.
If it's not out of tolerance, measure the resistance between the second and third legs of any of the muting transistors.
Also make sure that the preamp board connector is properly aligned.
