    I posted a while back that I needed a 100K 25V electrolytic cap for an
    Astron RS-50A Power Supply. I couldn't find one from the usual suppliers
    that would fit into the power supply case.
    I contacted Allied Electronics and the sales person got in touch with
    Cornell Dubilier Marketing Inc. They sent me two free sample capacitors at
    100K uf 25V. One of them is a perfect match for replacement. Since this
    capacitor isn't a normally stocked item it was sent as a free sample.
    Something to remember if you run into a replacement part problem. To try the
    manufacturers when you need something a supplier can't get for you as a
    single item order. I've gotten free sample resistors the same way also.

    I should have posted this as a Tip for parts.
    Sorry, George S

    Exactly what is a "100K uF" capacitor? ;-)

    Well it is an Electrolytic capacitor that looks like you should grab a beer
    can opener. Punch a couple of holes in the top and have a cold one.
    I wonder how many here still have a can opener like those in the kitchen or
    shop any more, or the all popular "church key"???

    I'd guess, 100 milli-Farads or 0.1 Farads. At 25 volts that's a heck
    of a lot of Joules.

    I calculate 31.25 J. re: W = 0.5 CV^2
    Are you turning dyslexic, Sam? ;-)

    Sorry, it seems I've had a brain fart. I see now that "100K uF" is
    just another legitimate way of saying 100,000uF, although to me it
    sounds unusual. I guess it's a bit like expressing 1V as 1K mV. :)
