ok, so ~15w output is plenty reasonable. Its actually better than I get from mine, so you've got something right. And thats with 0.46v input ?
Input sensitivity seems about right for the amp with feedback in place. I'd expect less than .05v input for full output with no feedback in place. It should be ~12db NFB which is more than a 10x reduction.
How much output do you get with the feedback connected before it goes funny?
