have built lm3886 based chipamp, on same pcb stereo.
thing is that when i unplug left channel ,signal from right channel input is heard at left channel output(and other way around),few db less than on right.
schematic is regular from datasheet ,100milion times checked and working in few other amps i make, only difference is it is on same pcb this time.
i am baffled and feel dumb ,but certain that i overlooked something very simple.
please help,ty
