    KP41EXR96

    Looking for the values of parts location
    R1728
    R1812
    Both on Convergence board :D:

    Thanks Much
    I think they are 1.ohm ?

    From memory: only take it ½ way to the bank.

    This unit has the convergence up front right ? If so read on. The only
    resistors it usually burns up are lil fuzibles or the yoke return resistors.
    The lil fuzible resistors aren't real critical, basically anything that goes
    off at the same current will do, but if they are yoke return resistors they are
    critical. They set the gain of the output stages and as such, if you change
    their value(s) you must do an unnessecary realignment on the convergenge.

    Look at the PCB, do they go between the Cyoke return and ground ? If so they
    are yoke returns and thus I would rather use used parts from a scrap board than
    a generic replacement. They must be non-inductive. Not sure if they're metal
    film or what, but they are not $0.13 resistors. They need to be accurate to the
    original value.

    The fuzibles really don't matter, it'll blow the 3.15 amp fuses before it cooks
    the SMPS, but it might cook a convergence yoke.

    There are six channels of output on that board, you just duplicate the values
    from another channel.
