Leach amp w/o feedback

How would you then define the Closed Loop Gain? would you also Reduce the Amps Origenal Openloop gain? I have used a Multiloop Feedback on the Leach Amp by applying a resistor from each side of the Voltage gains second stage to the Inverting input. Also the output stage is feed back to thie inverting input. The Open loop vs closed loop gain of the amp can now be easly controled. Other methods of reducing the Openloop gain include larger Emmiter resistors on eather the First Diff Amp or the Second Gain stage. Exparamentation in encouraged like i have also operated the output stage only Outside the Feedback Loop with the Feedback still taken from the Voltage gain stages as in the multiloop method. Anyway yave fun with this because you can the Possibilities are endless.
