    Fuse question

    I have an old pair of drivers rated at 25 watts and I would like to fuse-protect them. Can someone give me some help in determining fuse size?

    I REALLY REALLY don't want to blow these!!!

    Much thanks!!

    HI JBLROCKS

    I found a chart for determining fuse sizes.
    It on page 14 in the following PDF file.
    See "Fig. 3.9 Fuse Selector Nomograph."

    Protection Bulbs?

    I just had another one of those crazy ideas that just might work for your unique application. What about using the HF Protection circuit from a JBL TR125 to protect your driver?
    For details see: http://www.jblproservice.com/pdf/TR-Series/TR125.pdf

    Since, I don't know the power rating of the 2412 driver. I am not sure if this circuit is a practical solution or not. But, maybe someone else who knows the 2412 power rating could take this idea and run with it...
