Looks like that was a fun place to dig around in. The Scott sure is interesting. Too bad about the water damage, but I'm sure you'll figure out a way to salvage most of it. Lucky how the pipe leaked slow enough that it never flooded the chassis.
I was really surprised to hear there were two of those same Sentinel consoles in that place. I brought home one of those exact sets earlier this fall, in rather nice condition, including a good 19AP4. Turns out it's a nice performing set, and the cabinet is real wood veneers, not a photo finish that was so common then. Sure would be fun to know the story behind why the owner ended up stashing those two empty cabinets down there.
