  • Anotaciones
    • The Ondolinette 345U has no AVC.
    • The radio is for 130 V but with a "barette" (metalic short circuit strap on filament series resistor) it works on 110 V. Barette not to confound with a barretter tube or the dial lamp in the schematic ! The "barette" only changes the mains voltage applied to the tube filaments (see schematic for text "En court circuit sur 110 V").
    • There is an (external ?) option to make it work on 220 V by including a series resistor rated at 235 ohms / 0.35 A, here for the whole radio. Price of this supplement: 50 BFr.
    • This version has only 2 buttons instead of 3 on the other version. The button on the right has a combined function: Tuning and band switch.
