    Almost sure that I took it out from a Bose radio many years ago. Would like to have some info on this item like voltage ratios & current limits. Think it looks like it because there's a 'noise' reason for it but not sure, just thinking that it is for a Bose apparatus... See photo attachement.

    Thanks for any info!

    It is the same type of laminated toroidal we used at manufacturing audio equipment. Once I did find its website with data ; you will have to dig deeper in the era of switching supplies. (Billion electric)

    Your photo is rather blurry. Does the transformer match this one?
    The specs are clearly shown on the label.

    Thanks, Harald Kapp, for replying!

    This info is great, the only missing thing is the cables' colors for the voltages but that is something I can find by inspection.
