  • Anotaciones
    • This radio would be a renewed version of the Ondolina 28 (3rd gen.) .
    • It could also be used with a M35 power supply when converted to use Réseau1 tubes.
    • A separate internal battery for negative grid voltage is always present, even when fed with a power supply.
    • There is a suspicion that the Ondolina IV is the same as Ondolina 28 (3rd gen.). In those years, SBR had the habit to use Roman numerals after the name for its advertisements, where those numerals stood for the number of tubes and never were mentioned on the type plate. There are multiple examples of those Roman numerals in the SBR section on this website.
    • The price is without tubes.

    1 Réseau tubes: from the French word "Réseau" = powergrid. Tubes that can be heated with AC current in contrast with battery tubes that are heated with DC current.

  • 2,560.00 BFr
