    Hi there,

    I'm trying to find some information on a pair of WSW compressors, I
    just bought on eBay, but I haven't got much luck so far!
    So I was hoping that maybe someone here, had some knowledge of these
    and know were I can find some history and manual/schematics??

    I have newer heard of them before. The only thing I know is that it
    was Siemens who build them for WSW in the sixties...
    Does anyone know if they are comparable to Siemens U273 comp's or

    The only info I got is a number from the faceplate of the unit saying:
    K. NR. 601433 and serial numbers 441 and 442

    Here's a picture from eBay:


    It would really help me a lot!!

    Thanks so much!!

    Best regards,

    hi ziggy!

    i own three wsw compressors. they are not the same as those on ebay, mine are 2u rack size (little wider actually so they dont fit in normal rack) . as i know they were built by phillips for use as am radio final limiter. there are two models, difference is that one has additional peak limiter. the ones i own have really special agressive sound (they limit like hell!!), but they are a bit noisy. those ebay wsw comps look like modules from tape recorder or console, i saw wsw mic preamps in the same frame.

    hi ziggy,

    I've been eyeing these wsw compressor modules as well. how do you actually like them? what's the tonal character?
    I own a pair of siemens U273a comps and would describe them as "dark, creamy and slow" if that helps.
