    I'm building a flight yoke out of a 'gunners power control' yoke from a M48
    Unfortunately, I had to use 2Kohm potentiometers, because they were the only
    ones that would fit/were available
    This gives me a lousy axis resolution, as joysticks normally use 100K pots
    So I need a relatively simple circuit that, using the 2K pots, will give me
    a resistance of 0-100K

    note: the potentiometers control the discharge of a capacitor (timer
    circuit) in the sound card

    any help would be greatly appreciated

    you may be able to use a gyrator circuit to do that.
    Depends on dc levels, power usage, etc.
