  • Bemerkung
    • This is the first SBR radio where the tubes are not visible on the outside.
    • The retail price is without the tubes.
    • There are 3 models Ondolina 28 known to exist:
      • Generation 1: has a feedback1 regulator, no volume switch, and the switch for the scale lamps is just under the lid;
      • Generation 2: has a feedback1 regulator, has a volume switch, and initially the swith for the scale lamps is still just under the lid, then later it is on the frontpanel;
      • Nouveau modèle: has a feedback1 regulator and volume regulator. The switch for the scale lamps is on the frontpanel, jack for a pick-up at the back.
    • All generations are fed via connectors on the backpanel with a 4V and a 120V (storage) battery.
    • A separate internal battery for negative grid voltage is always present, even when fed with a power supply.
    • There is an alternative tubeset: HL410, 2x L410, P425.
    • The radio could be used with a M30 power supply, but also with a M35 power supply when it was converted to be used with a Réseau2 tubeset E430, E409 or E415, E415, B403 or B405.

    • 1 Feedback = reaction (regenerative principle).
      2 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.
