That's all I need for my horns. The Aleph J will do nicely in that regard.

For my midbass units, I want much more power. 150 watts will do the job.

So, my feedback isn't symmetrical. Guess I've got some reading to do, huh?

print that schmtc I posted , along with your schematic , then compare them ;

don' try to read Papa's SUSY patent papers - too confusing, but you can read his later pamflets on subject , they're much clearer

if you can't find them - all you need is to ask .

Until I hit the correct combination of parts and pieces, the sine wave looked more like something you'd surf. Here's a pic of the differential voltage taken at R27 (load):
