    Model (S)B14AU has a built-in autotransformer so that it can perform on 125V AC as good as on 220V AC or DC, a performance which is not possible working on 125V AC without that step-up tranformer. It is however still possible to function as a AC/DC device by bridging point 3 to 4 on the transformers board.

Hello,

Do You know this radio ? It is a Belgian one with the same chasis as the Sierra B15AU on radiomuseum.org.

There is no indication of any brand. Some work has been done trying to fresh up the radio. Knobs and dial have been painted in a strange color.

Please give me a sign if you know a radio like this.

 

best regards,

 

Eduard
