UREI came out with a solid-state version of these and called it the 1176. The earliest models were silver-faced with a blue stripe around the meter. They featured push-button ratio selection 4:1, 8:1, 10:1, 20:1, as well as attack and release controls. These blue-stripe ones are still in favor with many well-respected engineers like Bruce Swedien (Micheal Jackson, Jennifer Lopez...) .
