The Loricraft record cleaning machine is based upon designs originally developed by Percy Wilson, the late technical editor of Gramophone magazine, in the 1960s. The rights to the design were eventually sold to Terry O’Sullivan, who had established Loricraft Audio to manufacture plinths for Garrard turntables. The first Loricraft Audio record-cleaning machine (RCM) emerged in 1990. From the very beginning, Loricraft RCMs were designed for continuous running and built for commercial as well as domestic use. As a result, these machines have been widely adopted by radio stations, music retailers, and record collectors worldwide. SME acquired the Loricraft operation in 2018 and set about refining the designs. The new PRC4i and PRC6i machines were launched in 2021.
