How to Open a K2500 (76-key)

Discussion in 'alt.music.synth.kurzweil' started by ArchDeaconMalli, Mar 2, 2009.

  1. Anyone have a link to some instructions on how to open this keyboard
    to install some sample ram? The instructions at:

    http://www.k2users.org/k2/k_ram.htm

    ...seem to omit a few steps? I took out the screws mentioned, but the
    cover doesn't seem anywhere near coming off. Is there a step by step
    procedure somewhere that describes exactly what to do to open this
    keyboard?

    2. Start with the unit upside down and remove only 7 screws--6 on the
    76 key model. The screws attach into an aluminum rail you can see down
    the center.
    3. Flip the unit upright and remove the 10 back screws just above the
    seam along the back.
    4. The top is removed as follows:

    1. Place both hands firmly on the top of the panel on each side of
    controls. Push the entire top down and then push towards the back of
    the unit sharply.
    2. Lift the right end up a couple of inches, then pull to the right
    so the bezel for the disk drive clears the end.
    3. Carefully lay the top unit back top upside down on the floor. Be
    careful, because there are cables attached along the back. Don't pull
    too hard.

    What part of this didn't work?

  3. Where do you pour the chicken stock?

  5. I removed the screws mentioned. I have the 76 key model. There are
    what seems like two plastic "caps" on the sides of the keyboard.
    Following the remaining steps, (i.e., pressing down and trying to push
    it toward the back of the unit), nothing moves at all when I do this.
    It seems like the "caps" on the sides of the unit are preventing this
    (though maybe I'm wrong about that).

    Do you know if it would be true to say that all you have to do to open
    up the 76 key model is to remove those screws - i.e., that's all you
    should need to do?

    Thanks

    If ALL 16 screws are removed the case might just be stuck.
    You could GENTLY try to pry the case apart with a thin blade. That
    might at least indicate what is preventing it from opening.

    That said the K2500 is a bitch to take apart. It is not a simple
    procedure. That's why anything that needs to be installed is:
    "Not a user installable item - Must be installed by a Factory
    Authorized Service Center (installation charges additional)"

    You might want to call around and see what a repair shop would charge
    to install your memory. Could be cheaper than breaking your keyboard.

    Also consider the K2500 Service Manual:
    "This manual covers both the rack and keyboard models, contains all
    disassembly/assembly instructions, troubleshooting, calibration tests
    and all schematics of the Rev G models (30 pin SIMMs) and the Rev K
    models (72 pin SIMMs). You could practically build a K2500 from this
    book. Order part # 910292 from your dealer or call Kurzweil direct."--

    The end caps do have to be removed on every Kurzweil since the K2000 (which
    could be opened by simply removing the bottom panel). there should be two
    bolts in the back panel, three bolts on the bottom, and one additional on
    the bottom that is holding down a piece of metal that keeps the top part of
    the end panel from coming loose. Also, if you remove the end caps BEFORE
    removing anything else, you can look in to the unit from both ends, which
    may help clear up what else is needed.

    I've disassembled a PC88, K2661, PC2 all in this way. Never worked on a
    2500, but I expect that they are the same. REALLY be careful when you do
    open it not to break loose any wiring. When you close it, be careful not to
    pinch any wires between pieces of sheet metal, they will be shorted out
    eventually, with differeing results from inoperative scanning to letting out
    the magic smoke.

  9. Why are you even considering helping this nazi ****wit?

    At least give him instructions that will fry the Kurzweil. He deserves
    whatever bad happens to him.
