This design has a stability issue.
The DC output point (without input signal) should be 0 V with a small offset, but it's not the case, because this point is not stable.
Initially the amplifier had an offset of about 200 mV but it wasn't stable; it changed from 100 mV to 300 mV pretty fast (so fast that you can see 2-3 changes a second on a multimeter).
I tried to add an input signal and the amplifier itself worked well but the offset was always unstable.
After a while this offset started to drift and increased to 400 mV, 500 mV, 600 mV, and more, sometime it became negative, always with fast changes.
Every time I turned off the amplifier and then on again this offset increased, even if the amplifier was cold enough. Actually there is 2 V of offset.
The trimmer on R4 should set the offset, but it has no effect on the circuit, the offset goes its own way. There is a stability DC issue but I can't find it. Maybe something is wrong with the schematic?
