Hallo,
in this PDF you find follow sequence
1) Schematic - only for simulation, not for diy
2) Frequency Response
3) THD - I 100 KHz (10Vss output swing)
4) THD - II 100 KHz (10Vss output swing) another scaling
5) clipping behavior (10 KHz)
I have removed two capacitors: 680pF from output differential input stage to loudspeaker output and 10 pF parallel to NFB resistor. Additional I have introduce two resistors (15 ohms) in the source line of differential input stage. This reduce the open-loop gain and the risc of oszillation.
By original Version I don't get simulation results - only the error message "access violation" Please note, by this simulation all capacitors and resistors so as the voltage source (power supply) and input source (signal generator) are idealized (i. e. o Ohm internal resistance by the power supply). In additional there are no inductance and spread capacitance through PCB layout.
Only the effects of pure circuit are to see.
