ls2 is set to be stable at a certain gain deviation of such may result the circuit instability upto self-oscillations.
you may decrease the gain decreasing the values of the feedback resistors of an output stage or make it unity when you short the feedback path(using jumper instead)...
the DC supply may need to be revised for each feedback level used which dictates basically total circuitry redesign.
