    Strobe Flash Capacitor Problem - Fix?

    Hi Folks,

    One of my Multiblitz Profilite 200 flash units has blown a capacitor. Online sources have advised this is terminal for the unit Complete disaster, I haven't had them long and was just refining the technique to get good results, I'm gutted. They are not covered by warranty.

    First of all do you know if this can be rectified, then, is there anywhere I can take it to have it assessed in Melbourne and maybe fixed if it is cost effective.

    Thanks

    A "blown" capacitor would be ruptured. Sure a totall loss.

    To test if a undamaged capacitator is the source of the problem, a capacitator-tester appropriate for that high capacity must be used. (But I don't think such a tester woúld tell the wole story even if the capacitator should yield nominal capacity.)

    Mulltiblitz might sent just a spare capacitator, if that would be the cause. They most probably can name you an australian repairer.

    The parts in a flash unit are usually very densely packed. This makes trying o find a replacement difficult. While a particular capacitor might work electrically finding one to fit in the available space is problematic. There is also the hazard involved with the capacitor used in flash units. More than enough amperage to stop the heart.

    Somehow I don't suspect the capacitor in the first place.

    This is a well spread, old 200W/sec studio flashlight. The manufacturer is still in existance.

    If you can remove the cap, and take photo and measure the size of it, I will look in my junk box for you.

    Thanks folks for your thoughts. I've not responded because I've been away for a couple of days.

    I spoke to Fotoriesel who are the Australian distributor of Multiblitz and they don't have a service agent currently in Melbourne.

    Johnkpap, that is very generous offer which I appreciative. I have pulled the front off to find a tangle of wires and diodes that I'll send through photos of to see if can make sense of it.

    Tom, what do you think it might be?

    If you are going to work with a flash gun or any electrical power you need to first put on the pukka safety glasses and only then open the unit...

    Capacitors in any device have failure modes where they explode and you can be a long time blind. The report is like 0.45 long colt, the bits of the casing of the capacitor go a long way.

    Apart from the jolt you can get from a capacitor hurting good at the very least, they can hold charge for a long while after they are off, and still hurt good.

    The flash caps are high voltage rated the suppliers should send you a suitable replacement.
