• This is the first SBR radio with built-in loudspeaker together with the Ondolina Réseau 311.
• Internally, the radio is divided into 2 sections: the radio in the top half and the power supply in the bottom half of the housing.
• There are 2 known generations of this radio: the 1st generation has a filament rheostat on the backside and without a voltmeter, the 2nd generation has a rheostat and a voltmeter on the frontpanel of the loudspeaker (see photos).
• In case of the batteries version, the power supply section is left empty to make room for the (storage) batteries.
• The AC mains version has an "Oxymétal"¹ rectifier and a voltage selector for 110, 130 and 220V.
• The DC mains 110V version and the DC mains 220V version have an internal resistor block to adjust to the mains voltage.
• All versions of this radio still need an internal 15V negative grid voltage battery ("C" battery).
• There is an alternative tubeset from Dario: R83 , R78 , R81 , R76 , R79.
• This radio was delivered with a loop antenna 351.
