The forum software only allows a limited number of file extensions and 'asc' is not one of them. To post the LTspice file, rename it first - change foo.asc to foo.asc.txt or foo.txt before you upload it. Those downloading it does the opposite before using the file.

Alternately, you can zip the file and then post it.

This looks like a simplified hafler frontend coupled to a triple outputstage. I think its patented, will have a look see on hafler schematics. Should be fast with lowish distortion.

Nice Distortion distribution.
