This tube is the forerunner of the UY224 and was made by a few manufacturers such as Arcturus (122AC), Ceco and Eveready Raytheon (AC22), Sonatron, Songbird (made for Montgomery ward) and Sylvania (AC222). These tubes were available for only a few months - April to July 1929, when the type number was discontinued for these.
