I have a short free time at the afternoon, and it’s time to test my Power Supply for my Gainclone. Powered by Talema dual secondaries, each rated at 18VAC/6.3A

psu_all

I setup basic configuration with dual bridges (8x MUR860) and 35 pcs of Black Gate F Series 680uF/65V capacitors each rail. I plan to add Snubber with new Duelund CAST Resistor and MKP1837, some bypassing with either Auricap/Mundorf/Jensen, and some experimental “off the record” LC configuration ;)

psu_positive

The last thing that I have to do is to check the voltage for the positive and negative rail. Well, I have to make sure they are within my standard of tolerance.

psu_negative

The positive rail measured at 26VDC, while the negative rail is at 25.9VDC. About 0.3% is considered OK.

Another photo below is for the close-up shoot of the capacitors.

It’s time to power up the Gainclone. Sorry, it’s too late. I hate to work – especially when related with something which needs extra cautious – but with less concentration. I will delay the power up of my Gainclone for few more days…

    look forward to read your next journey Mr. JA.
    seems this 1875 will look promising.

    Kayaknya mas jimmy layak masuk rekor MURI nich, untuk kategori “Penyolder BlackGate terbanyak di Indonesia”

    So I don’t under stand why you have so many Caps in a line? What does this do? Is this for Breaking them in or something else?
    However you slice it I like the website!

    Hi,
    Many caps in parallel will lower the ESR which will reflect in the better supply performance.

    Thanks.
