    1. Combinaison 13 with RF and detection stage, 2 tubes
    2. Combinaison 34 with detection and LF stage, 2 tubes
    3. Combinaison 44 with 2 LF stages, 2 tubes

    6. Combinaison 1344 with RF, detection and 2 LF stages, 4 tubes

    Explanation of digits in "Combinaison":

    • "1" = RF amplifier tube
    • "3" = detection tube
    • "4" = LF amplifier tube

    The mentioned sale price is without the tubes, which were sold at 30 BFr a piece.

    These amplifiers and associated Radiolina 1 and Radiolina 2 models are probably the first radios sold by SBR. A chronological list of SBR models can be found here.
