At 1.2W power output with 1KHz sine test signal:
Left Channel : 2nd harmonic = -44.44dB, 3rd harmonic = -46.68dB,
4th harmonic = -66.54dB, 5th harmonic = -73.93dB
THD = .77% THD+N = .79%
Right Channel : 2nd harmonic = -43.71dB, 3rd harmonic = -48.21dB,
4th harmonic = -66.05dB, 5th harmonic = -76.27dB
THD = .76% THD+N = .79%
Took these measurements tonight.
2nd and 3rd harmonic seem to dominate the spectrum in this circuit.
