Being a perfectionist is not easy (and not cheap). Still remember my ambitious project before? I want to make it perfect, so let’s start the 1st phase, testing the capacitor (I mean, the Black Gate) ;)

I will use 60 Black Gate capacitors on the power supply. First 30 pcs for positive rail, and another 30 pcs for negative rail. I want both rails have similar capacitance (or as similar as possible). So first capacitor on positive rail will have similar capacitance value on first capacitor on negative rail. Too perfectionist?

I need to know exactly the capacitance of each Black Gate. You know that every capacitor has around 10% tolerance. So when it’s written 680uF, it may vary between 680-68 or 680+68. Who knows? The meter knows.

I write down all the values one by one on a piece of paper in the form of 10×6 matrix. Then, I sort it one by one (well, with the help of Microsoft Excel). It takes few minutes to accomplish this simple task with Excel. Below is the sorted value.

Now we start the “game” to put the Black Gate in correct position. Move move move!!!

Task accomplished! Both channel will have similar capacitance.

    Aha! Brother Jimmy is playing Checker with BG! Or Trying to solve Sudoku Quiz?
    Hahahaha… the next question is : Are you ready to solder those pins?
    May The Force of The Solder be with you
    :))

    beli meterannya dimana bro??..Pengen juga tuh punya meteran kayak gitu..Biar tau bagus apa kagak

    @Dino Ary:
    Dipajang dulu aja bro. Siapin tenaga dan semangat buat nyolder hahaha.
    Masih lama kayanya huehuehue…
    Thanks.

    @Damar:
    Di Glodok ada jual.
    Tapi bukan tau masih bagus atau ga, hanya berapa capacitance-nya.
    Thanks.

    eh iya..ada yang lupa..kan di rumah DIY audio..masalahnya gak pake filter di bagian input ke trafonya (220V).Kalo aku mau pakein kapasitor AC (NP) pakeinnya gimana??( paralel dengan PLN atau seri dengan salah satu kabel input tegangan trafo)..Thankz..

    pak Jimmy..
    loh kayak mau ngitung nomor buntut
    heheehhehhe
    ntar di pajang fotonya yang sudah di solder yah..

    I wonder if the capacitance will be change after break-in period, can it?

    It shouldn’t…

    Thanks.

    Almost, nambahin 10 BlackGate lagi. Sama nungguin Trafo Talema-nya.
    Thanks.
