Yet another one. This turned out pretty good with extremely low THD, bordering on almost no THD. I suspect the 2 feedback system (local,total) to be partially responsible for this. Anyway the specs are : - Input Impedance - 14k - Output Impedance - 22k - Gain - Fixed at 4 - Frequency Response - Hard to say, because -3dB would be a big difference, but it's good from 20Hz-30Khz - THD+N - 0.01%
