The Lyra fourth-class radiola was developed at the Krasny Oktyabr plant and was produced by a small experimental batch. At the end of 1962, all the technical documentation for the radio was transferred to the Vladivostok plant Radiopribor, where the radio was mass-produced from the beginning of 1963 under the name Serenade. All technical characteristics of the "Lira" radio correspond to the characteristics of the "Serenada" radio.
