Alternative tubes: Marconi 'R'.

This amplifier was manufactured by SFR, but SBR retailed it under their own label. The following 6 variants were available:

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

5. Combinaison 344 with detection and 2 LF stages, 3 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.
