Younger brother of the LM3886 - LM2876 in parallel

This was the answer I was looking for, you know this stuff Jean -paul

Well I for sure don’t need to ask such simple matters so maybe you should follow your own advice. Copy the circuit. Connect inputs to eachother before resistors. Put 0.1 Ohm 5W resistors at each ICs output and join them at the loudspeaker outputs.

It is wise to use very low tolerance resistors when using the ICs in parallel.

These will do the job 5w 0.12r

You can use 0.12 Ohm 5W but I advise to use 0.1 Ohm 5W 1% tolerance. And the other resistors even 0.1% like in the datasheet/evaluation board schematics. Now you tell me why that is.

Do not use stuff you happen to have but use the correct stuff for the job. Better approach if you like success.

Is tolerance of balancing resistors more important than DC offset difference?
