« Last post by xvr on Today at 05:02:44 pm »> For that i need to tune the bias for my single amplifier and to tune sepratly for the pair.
Nothing. Your schematic do not depends of amplifier current (6A for single, 12A for pair), only for amplifier voltage. Voltage the same for both single and pair.
But you need 3 identical channel (including DC/DC and UCC) for control 3 independent subcircuit (1 single + 2 pair)
PS. Consider P channel MOSFETS from my previous post - your current schematic became monstrous
