So I found this on the Bay, not much info about it but I think it was designed by a gentleman named Kevin Halverson. It is missing the volume control, one output RCA and the power cable from the power supply to the preamp. The damn power supply weighs 40lbs and looks like something you would use for an amplifier. I think this sat on someone’s garage bench for a couple years with the lid off because it was filthy inside. It is missing some standoffs and screws but I don’t see anything burnt or damaged. I cleaned off all the boards and removed a couple decades of grime.
I was thinking this might be a cool project to learn on and might make a good addition to the collection.

Tomorrow I will take high resolution pictures of each of the boards, hopefully that will make easier for you to decipher. I haven’t found schematic for it from the usual sources. I appreciate any info you guys can figure out.
