LM3886 x 3 continue
The DC offset of the three 3886 are interrelated. Hence, adjusting them all 0.0 mV is tough if not impossible. I now made them all 8.9 mV to achieve DC balance. Next will adjust the AC gain. DC offset may need readjust again. This is a game for $ (cost foe DC servo) vs time.
The three 3886 have identical batch number.
