KH3477 was a television model produced for RCA. Released in 1979, it was a color television, featuring a 23.5 inch diagonal screen and a built-in Comb Filter that improved picture clarity by reducing line flicker. The set had an analog tuning system, one composite video input, and a separately sold optional remote control. The television was designed to fit into a standard entertainment center, requiring only a 19-inch shelf space, and was designed to offer a great balance of features and value.
