    Model (S)B10AU 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.
     
    Same chassis as Philips 529AU.
