That tuner is for sale locally, I had no idea what amp it went with, maybe I should pick it up, the rack would be impossible to find.
I've got a handful of branded racks but they are the cheap pressboard covered with vinyl. The bottom is usually a record rack and the top has a hinged clear plastic cover for your record player. These were pretty popular over here, I never saw a better "industrial" rack with or without rack mounting. I wouldn't want to put too heavy of equipment on mine but they can look neat with the right gear.
