MADE IN BULGARIA 1962′s. Elprom KB (Kliment Voroshilov Works, Slabotokov zavod); Sofia. One of the last Bulgarian Bakelite radio receivers, of course – IV class. Transformerless supply, U series lamps (parallel connected) – UCH81, UBF89, UCL82, UY85. Extremely small and light. We’ve always thought it was particularly beautiful – we love the contrast between the raven black bakelite and the snow white plastic grid.
