Post your voltages of the compander (v571).
You should have -4.7 volts on pin 7 of V571 and -13 volts on pin14 & pin15.
Gain 1 and Gain 2 trimmers affect the repeats.
If everything looks right, check the resistors after the compander till the FBK pot (r12,r14,r17,r19,r21,r25,r26,r27,r32,r33).
Cheers,
