  • Notes
  • 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.
  • There is another version of this model that has no tuning scale and only 2 buttons instead of 3: see Ondolinette 345U without tuning scale.
  • Price in first year of sale
