In Reply to: Oh, you mean like Stu Hegemen and David Hafler... both used positive feedback to reduce distortion~nT posted by Cleantimestream on August 4, 2013 at 14:51:05:
I can't find any doing an internet search. The only positive feedback electronic use I can find is in digital circuits to insure that an output goes to a clear value instead of an intermediate value (the voltages representing 0's and 1's). I found a reference to using positive feedback early in radio history to amplify very weak signals, but the operator had to be ready to intercede when oscillations were induced. I see that positive feedback has been used on input impedance matching circuits, but they only work because the amplifier section has a gain of less than unity. Maybe positive feedback could be used to form oscillators, but I know of no use of it for the audio amplification path.
