    HI,
    I don't understand power cords and adapters / transformers all that well. Probably just well enough to cobble something together to run some LEDs but this is throwing me.

    I have an old knitting machine. It is telling me I need an AC output of 9.6V x 2 1.6A. This information is from a European version of the machine. Input of 240 50hz. Thats the info I have at this point.

    I need something to run the US version of this machine which is 110v, and the same output.
    My question, what is meant by the x2 in the output. That is throwing me. I am trying to build a cord that will power the machine.


    Just in case someone knows where I could find it the original power cord is an SEA-2, for a Singer/Studio/Knitmaster 500 or 560 or 580 knitting machine. The brands and model are all interchangeable.

    I presume they're saying two separate outputs of [email protected]
    If you run it at 60hz the motor will run a little faster than the original 50hz. If there is electronics involved that difference may be a problem.

    Can you post a picture of the plug/back of machine where power cord is?
    It may clarify your situation.

    And, are you in Europe, or the US?
    What mains power are you using?

    I cannot get a picture of the plug at present. Have to wait until the machine gets to this house. Week to 10 days. I am in the US. As I recall, the plug is a 2 prong plug, I will get a picture as soon as the machine gets here.

    While waiting, here are some resources. The last one has free service manuals for all models that include enough information to reverse engineer the power supplies. The two 10VAC inputs are converted to ±5VDC and +16VDC supplies with a common ground. The connector types used are not well described but if a working, or even inoperable exemplar could be acquired, a workable substitute for the AC portion alone or a complete AC/DC unit could be constructed.
