    Hello All,

    I have a set of RTR 180D Spkrs The Slave cabinet unit internal crossover cct has a press button reset style switch lablelled : littelfuse inc 230 815/series.
    This appears to have gone open cct but I have no idea what it actually is or what I can replace it with.

    CCT description::
    One side of the BASE Spkrs are feed directly from the input socket, the other side from the output of the crossover network which is 15ohm ?? pot to 2 x 6uF Caps in Parallel to "Littelfuse Reset" to 2 x 5ohm 10W parallel resistors.

    The tweeters are feed one side from Input Socket the other from the POT.

    Any help greatly appreciated.

    The device seems to be a 2AG fuse. You might see if it is blown (you will need a meter), and what failure made the fuse blow.

    Hi Beenthere,

    Tks for the reply, was wondering if that is what it was; seem a lot of trouble to have a sealed unit with a push button reset ?

    Will try disconnecing and putting a 2a fuse in its place.

    Tks
