Vintage HP power cords needed.

    I am looking for some vintage AC power cords for older HP test equipment.
    I have a number of pieces of test equipment, and only one power cord. The
    only marking on it is "Electricord". It is a three conductor cord that
    uses three round female sockets on the end that terminates at the
    equipment, and is similar to the old power cords that were found on coffee
    pots and such (but with one more pin in the center offset from the other
    two - a ground, I suppose). I believe it is typical of HP equipment made
    in the 1960's to have these, such as the HP745A AC calibrator, among
    others. Does anyone know where I might find some of these, or perhaps know
    what the original HP part # is? (I know that I could hard-wire a standard
    line cord to these units, but would much rather have the proper cords.)

    Thanks!
     
  2. If they are the same ones used on old electromechanical Victor and Burroughs
    adding machines, I have those in stock. Send e-mail to
    .

  3. Be aware that there are two different pinouts on these cables.

  4. Good morning.
    On these, when looking at the hole end with the center hole towards the top,
    left hole is hot (black wire), center hole is grounding (green wire), and
    the right hole is grounded or neutral (white wire).

    Thanks,

    Hello Lee,

    Jeez, I don't know. Do they look like this?:

    Also, is the center conductor ground, or can it be re-wired if not? (Not
    molded)
    How many do you have and how much are you asking for them?

    Thanks!

    Hello Michael,

    Thanks for the info. Perhaps they can be rewired, or if it comes to that,
    I suppose the male ends can be cut off and rewired.

    I should probably also mention that the width and length at the end of the
    thing is 15/16" x 1/2".

    Thanks again.
     
  7. Good morning.
    That looks like it, except these are gray. In your picture, the hole on the
    left would be grounded or neutral (white wire), the lower hole in the center
    would be grounding (green wire) and the hole on the right would be hot
    (black wire).

    These are factory molded on both ends, you cannot get to the wires without
    cutting.

    Thanks,

  8. Good morning.
    That is what these measure. If by chance they would not fit, or are wired
    wrong for your application, I would gladly take them back, including the
    original shipping or postage. The office machines using these cords were
    made in the late '50s or early '60s, and used on up until the early to mid
    '70s when the 3 slot IEC type became more popular.

    Thanks,
    Lee

    Hello Lee,

    They sound good! How many do you have for sale, and what would the cost
    be?

    Thanks again!

    These may even still be made by Belden; they were just a few years ago.

    Just be glad you're not looking for a cord for a Wollensak tape recorder.
    It is very similar-looking but not actually the same as these...

    The last time I looked for these they were available in office supply
    stores.

    Let me make this clear.

    **** OFF

    Power cords do not influence sound. Anone who thinks so is a RETARDED
    'know-nothing' FUCKWIT.

    SOUND??? WTF have you been smoking? Perhaps you need to go back and
    re-read the thread, thimble wit?
     
  17. What? I agree that power cords don't infulence sound, but nobody said
    anything about sound or even performance. He has equipment with non IEC
    connectors on it and doesn't want to have to solder a power cable on it.
    Read the OP.

    There was a discussion here (sci.electronics.equipment) several years ago
    that included the Belden part numbers.

    Looks like I saved it. Here's the highpoints (minus the flamewar).

    Ah, you must understand, He's one of those undesirables that his country
    folk would love to lock up and throw the key away..
     
  20. This probably isn't up to code, but for my function generator I cut the
    end off another cord and crimped yellow (12ga?) but splices to it.
    Slightly crimping the other end made a socket that nicely fits the pins.

    Looks ugly, but works.
