Class A with LME49811...

[Dxvideo]

Once again: you don't need 2.5 A bias for 25W/8R.
1.3A is enough because:

as AndrewT wrote already in post #10 and bobodioulasso in post #7:
"A push pull amplifier reaches the ClassA limit at twice the bias current.
Most will then go further operating in ClassAB. Read the F5 article to see how it's done."

Now, I exactly understand what Mr.Pass meaning with F5 article... In fact I am surprised that why I couldnt think that before! Totally logical and I will go this way. So my LME49811 project will run at 1.3A bias.

Thanks Juma and especially Mr.Pass
