Its their old Terminator series high current amps... I picked one up for cheap that works but it appears to be modified. Theres an extra cap in there and a few other suspect parts. I am trying to restore it to original condition but i cant find a picture of an original board. I will try to post pics up later of mine so you can see whats goin on.

looks like I need a 50V 1000 microfarad cap. Under the power wires on the first pic in the top left side is there a small resistor covered in heat transfer paste?

From what I was told and I do not know if this is true or not, But Special Edition turned into PPI.

Man those were some amplifiers back in the day, Spendy stuff too.
