Oh you think input caps are extra
Yeah it still works..
Is there a DC voltage at the input now? If so, don't connect it to any other source
unless that source has a blocking capacitor at its output.
My bet is still for oscillation.

Thanks rayma.
I just 2-3 seconds shorted the input cap.I think it is still ok..
Maybe these can help..
Do you have a schematic diagram?
Also, Is this a new, unproven board and circuit, or has it been successfully built before?

No,I made it with diptrace..
You can see the image just I used R-ch of the diagram.
2 bypass caps(*2) for each ripple filter cap and main filter cap.
I connect the stb pin to directly to main voltage.
That's it.
If it helps, I can draw the schematic..

You've used one channel in each chip? Why?
I want it to be stereo without btl.
I think it maybe helps crosstalk and I can also use it with headphone-power amp adapters..
I see. It's probably ok to leave one amp disconnected, I'm not sure, maybe someone else would know if this might be an issue
I also short the unused channels to gnd.
But it didn't make any difference..
How does the noise level compared with the pot set around mid way?
It is like half noise maybe ?
