Three or four years ago when I needed a schematic I e-mailed Anthem/Sonic Frontiers and they sent me the schematics and the trouble shooting guide the next day. I still have them. Also I spoke to the guy at Parts Connection and he could rattle off all of the best upgrades for that amp right from memory (I believe that he was one of the original designers). Any of that info can be had in a day or two.
