• Notes
• Radio miniatura a 2 valvole + raddrizzatore. Mobile in diverse varianti di colore (bianco, amaranto, verde scuro e grigio). Guida Pratica AR V indica anno di produzione 1950, ma la valvola ECH81 è entrata in produzione uso solo dal 1952, e pertanto l'anno è successivo a quanto indicato.
  
  Miniature superhet, featuring two tubes and one rectifier. Several colour variants (white, amaranthine, dark green, grey). According to the book Guida Pratica AR V, the radio was made in 1950 - this must be wrong, since ECH81 was introduced in 1952.
