Would there be any chance of Outlaw releasing service manuals for your amplifiers? It would be great to be able to maintain these units for years instead of sending them to the landfill if/when they have problems and are past the warranty period. All that is required is a schematic, PCB layout, BOM and a simple instruction for setting bias and/or DC offset.
I have an old Harman/Kardon HK6900 from 1990 that I was able to repair and keep going because a detailed service manual was available for it. As well, I have my dad's "antique" Realistic amp that I was able to repair/restore because a schematic was available right in the back of the user manual.
Just an idea.
