    You could try measuring a know good capacitor with a resistor in series with it. Say 10 ohms or maybe less.

    EDIT: all the info is in the atricle.

    Built mine from the Altronics Kit many years ago as a novelty.
    Essential piece of test gear now.

    use a prescision resistor.

    You will usualy find when the caps are faulty their ESR is very high compared to a good cap.
    Don't worry, it only seems kinky the first time.

    dead right azza, anything with protection circuitry that wont let the bugger even start, the other way is to disable the protection circuit, but dont do it in front of the customers, they dont like to see smoke for some reason....

    dont know why, it makes it much easier to fix.
