The reasoning I am using such a high value capacitor is due to it high pass nature it creature with the load, the higher I use the likely hood it will pass all the output signal to the output stage.
Dual Audio Operational Amplifier
What’s connected to the output? Increase the load to 2 kilohms.
A load resistance of a few kilohms will reduce the DC output to a few millivolts Or replace the capacitor with a lower leakage type film cap or ceramic.
It will be utterly hopeless driving 10 ohms.
An oscilloscope is only connected to the output, i double checked, but its on the board board with many components on it, maybe that could be it? But that makes a lot of more sense, thank you so much for shedding some light.
Caps hold a charge voltage if there is no load. If a lower one would be used it will attenuate the signal at the output.

TonyEErocketscientist You were rocket my apologize, adding a load fixed the offset issue. What happens if you put a K pull-down on the output? Note there is no need for such a large value: Dwtasheet the resulting DC bias is a problem, there are 2 options:. Other parameters, for a load of 2 kilohms Power BW page 3, figs 6,7,8 and others. What’s the leakage current spec on the 1mF cap?
