So the A70 can output 2x180 Watts at 4 Ohms on both channels, in a short peak? I think it is capable of 2x125 Watts at least under 1 percent distortion. I'm sorry that it wasn't measured on Amirm's machine...The 5A is the same, but with two channels of simultaneous output and a maximum power of 180 W x 2. The inductor is of excellent quality and does not need to be replaced.
Thanks
