    I know nothing about them but I can tell you that they'd only work on the secondary side as the top voltage is way too low. They need to be capable of 400Vdc for primary duties and those only do up to 100Vdc.

    Mallory? Holy cow! Are they still around or is someone else just using their name?

    The company we now know as "Duracell" used to be "Mallory" until Proctor and Gamble bought them in 1996.

    You may not remember, but that "Mallory" logo used to be right over the word "Dura."

    Mallory made a few different electronics, like flashlights, switches, etc. and did have caps called "Duracap" (go figure) but I hadn't seen those since I was a kid.

    They still use the Mallory brand for their non-alkaline batteries: http://www.duracell.com/procell/products/mallory.asp

    I remember Mallory batteries, flashlights and such but I wasn't sure if the caps were of the same family. There's several Mallory's: Mallory batteries, Mallory ignitions, Mallory metal for balancing crankshafts...I hate jumping to conclusions because it's too easy to slip and bust my ass.

    Yeah. But the logo is identical.

    Unless it's a rip off company like Rulycon.

    On a quick look / search I found no mention of Mallory caps.

    madmat, it's been > 10 years since I have heard or read the term mallory metal and it's been 5 years since I ported a head.
    Worth a good looking over. http://www.badcaps.net/

    You knoe what might be intresting, if someone made a guide on how to re-cap PSU's with better caps, perhaps how to build your own using an older psu as a guide, I know Oklahoma Wolf is make a quide on rebuilding antec true powers.

    Seems to me if you have a good base, can you make a better output PSU(recapping a decent 480watt, and making it a better 650watt?)

    Maybe I'm just off my rocker :P

    That's the whole point of this:

    We have load and ripple results of both PSU's and will soon have them for the units after the cap job.

    Oh I thought he was just rebuilding them for the sake of getting them to work again, sounds good. I shall moniter that thread then, sorry for my momentary slip of stupidity and ignorance.

    Naw... they were both working (if you can call it that) already. The Neo's results will be most interesting since the Fuhjyyus showed no outward signs of failure yet.

    I think I still have an old Mallory in one of my Flukes.
    In the past I used to work a lot with Mallory parts on the HT side of car electrics, lots of distributors and coils that sort of thing, never seen the Mallory metal... I always drill off, not add. I also did not know that they became Duracell, that is a surprise I just thought they got lost like some companies do.

    Did anything come of the re-capping/ ripple testing ?
