    Why has it got to be Cheap !!
    Even a very good one is not expensive.

    Buy it in Italy!
    Cheap but professional, in Kit at the most professional kit outlet here.
    Costs 21 euro plus shipping plus eventually the magazine at 4,10.
    I've been using it for long time to check caps on bloody tv. Just today I
    solved a problem on a Sony.Perfect!

    Here details:

    Believe me, very performing!

    That's a new one to me. :) ESR meters and schematics for them seem
    to be popping up like mushrooms these days. Which is good, because
    they do save a lot of time when repairing gear which is more than a
    couple of years old, or which runs hot internally.
    I just did a Google search for --> ESR meter site:.uk <-- which
    brought up a variety of sources for them in England.
    Good luck. :)

    Thanks Ross. :)
    I collaborated closely with EVB in getting that version of the
    meter finalized. It does have more protection against charged caps
    than my original circuit (big fat diodes). The components are high
    quality, plus it uses the very bright red Kingbright displays I
    originally specified, whereas the DSE meter has cheaper
    moderate-brightness orange displays.
    I think the EVB meter's really good. :)

    Regards,

    I've seen posts on the ESR meters here and there and though I've thought a
    few times of getting one, haven't as yet. Who distributes the meters in this
    thread - of Mr. Parker or whomever? I seen him list EVB, I'm not familiar
    with them - at least not to my ever growing feeble mindedness and subsequent
    knowledge or lack thereof. What sort of price tag are they carrying. Also, I
    seen one made by Tenma, is it of any quality? I'd like to buy a good one
    when I do go to buy one. Any I should look at if I can't find "a" particular
    model/brand? Any I should definitely steer clear of? Any particular specs it
    should have to make it stand out over another model?

    Thanks,

    John's Jukes in Vancouver, BC (on Main Street) distributes a good one. I've
    been in there a time or two.

    One of the mentioned units is an adaptor for a multimeter. Interesting idea.

    Ugly or not, so long as it gives me the info I need, I can overlook the
    rest! At least you have one. I'm still stuck in the 19th century waiting to
    get one online. One of these days!!!!!! Thanks for the tip, I'll check it
    out.

    I notice that the ESR comparison page states that Anatek ceased to
    carry the Dick Smith kit
    http://www.dse.com.au/cgi-bin/dse.storefront/424cf88109b9f468273fc0a87f9c075f/Product/View/K7214

    "Anatek experienced degradation in the components supplied with this
    meter and stopped carrying it in March 2005."

    Without knowing who was making up the kits Anatek was stocking it is
    not possible to know where the fault lay with regard to the alleged
    "degradation in components". Bob Parker, the designer, specified high
    quality but readily available components even in the Mk1 version
    described in Electronics Australia, January 1996. Resistors were
    specified as 5% (which would have been carbon composition), except for
    the critical units which were 1% metal film. Capacitors were either
    MKT film, RB Electro's, monolithic X7R or ceramic NPO as the case
    required. Given the possibility that the Anatek kit supplier may have
    deviated from the original parts specification it might have been
    possible for the degradation to occur, but it would not have been the
    case if Bob Parker had any say in the matter. At the time of the Mk2
    release in April 2004, over 12,000 Mk1 kits had been sold, most being
    made to customers outside Australia. Surely this is testament to a
    well designed and reliable unit. With the release of the Mk2 kits in
    April 2004 all resistors are now specified as 1% (which means all
    metal film) while all other components are still high quality units.

    For those in the USA you can obtain the Mk2 kit from John Juke's
    http://www.flippers.com/esrktord-form.html or Main Electronics

    The quality problems we encountered were poor pc board tracks and
    holes making reliable assembly difficult. There were also missing
    parts. That was more than a year ago, so perhaps those problems have
    been solved.

    At the same time DSE mislabeled a large shipment to us but charged our
    credit card anyway. We found out about the mislabling when one box
    out of the four arrived by some miracle. It had no city, state or zip
    code on it and the street address had no number, just the street name
    but somehow made it to an ajacent town whose name is the same as our
    street name. The postmaster looked AnaTek up in the phone directory
    and found us. That is how we saw the mislabling.

    DSE insisted that we pay for the entire shipment and we refused and
    disputed the charge. The shipment costs were charged back to DSE who
    now refuse to ship with us as if all this were our fault.

    Therefore, we can no longer offer the DSE items. Frankly, I miss
    handling Bob's designs as they are good, but I do not miss DSE.

    I was always afraid that things might get this bad after Fiona left
    DSE, and unfortunately it got even worse than I imagined was possible.
    It's a pity that EVB aren't interested in producing and selling
    those ESR meters at a sensible price and in quantity. Oh well. Just a
    few thoughts I've been having....

    Maybe a DSE person is lurking about here. If so, maybe he will pick
    up the ball and run with it.

    I sure hope so. Hate to lose a good product because of organizational
    stupitidy.

    Most of us here in Australia don't miss DSE either. Once upon a time they were
    a valid part of the electronics scene. But that was a loooooong time ago.

    Years ago I wouldn't have said anything negative about DSE's
    service to overseas customers. But the ongoing sloppy careless
    couldn't-give-a-damn attitude of the people who replaced Fiona is so
    well known that I'm not going to defend them.
    That's the reason that I've got the EVB version of the ESR meter at
    the top of my ESR meter web page. If DSE loses a large chunk of their
    overseas sales of the kits, it's because they brought it on
    themselves. I just wish that EVB would make and sell that version of
    the meter in quantity at a sensible price.
    Thanks for your nice thoughts about the basic ESR meter design.
    Much appreciated. :)
