After over 2 month of laziness, finally I finish the tiring job, soldering 60 pcs of Black Gate F Series for my Gainclone Power Supply.
Well, practically, this is not only for Gainclone. The design will be quite modular, as described below:
- Dual rail design, for positive and negative
- Each filtered with 30 pcs Black Gate F Series 680uF/65V (around 20.400uF total capacitance each rail)
- Choke Input Design
- Main rectifier is 4xMUR860 (600V, 8A)
- Snubberized Design with Mills Resistor and Russian PIO/Teflon Capacitor
With 65V working voltage of the capacitor, this modular power supply could be use for many purpose. Let’s say, a MOSFET project? 😉
Well, as I’ve told you. I love a “neat” design. So cosmetic should be one of my main consideration. I use small fabric cloth to cover all the capacitor leads. All capacitor connected via a thick 2.5mm copper wire, wrapped with its standard “heat-proof” insulation.
The final appearance of my Black Gate troops. I just need to add the MUR860, choke, and Snubber parts. Oh well, we’ll see when I have extra free time to do this.

Thanks.

July 11, 2009 04:59waste of money + time, what’s the use of black gate f series on a supply board?
Max Jeorge
July 11, 2009 07:51Those black gate has amazing sound and filtering capability in psu application. I assume you never try any, fixer?
@Jimmy:
How does it sound man? I have tried with 4 black gate in my gainclone and it sounds wonderful. I use Nichicon and Elna before though.

July 11, 2009 07:58@Fixer:
Perhaps you are right, it’s a waste of money and time. But since right now I have them both available, so it’s not a real problem to try a “full blown Black Gate” power supply board. You can try to look elsewhere to find reason why a capacitor named “Black Gate” is praised in the world (and why people would spend extra money and die for it). After you got that, perhaps you will know my reason to put so many on my PSU board (and perhaps you will also curious to listen the different).
My experience, power supply has significant contribution in audio application, as food for human. Good and well designed power supply may contribute over 50-80% to overall sonic quality.
Thanks.
@Max:
Not yet finish with the rectifier and snubber.
Thanks.

July 11, 2009 17:39I know what the black gate is, and its capabilities, on a gainclone, i would use them as on board reservoirs near the psu pins of the chip and it would be really useful because of high ripple current capabilities, the amp will easily can get the peak currents required. But i would prefer two of big low-esr, high-ripple, high temperature (e.g. evox-rifa peh169) caps on the psu, instead of 60 small black gates. Psu caps must clean the power well and make it stable. A hi-temp, low-esr cap is more important on the psu section i think. Ä°f you made this unit because you had the caps already in hand, i just can say it’s good looking, but technically required? I think not. By the way, i would not use that thin wire for a 6800uF cap.

July 11, 2009 22:47Hi,
Thanks for your attention. Don’t worry, the on board PSU near the chip also got the Black Gate, bypassed with oil caps, for smoother mids.
I have some high ripple, low ESR caps like Nichicon, Aerovox, Sikorel, etc (you can see my collection on other post). But so far, none could provide the sonic signature like Black Gate (after break-in period). I also love Elna Cerafine, but dont have enough on hand. Sikorel also very good, but again, this is one of the rarest on planet.
I have experiment with lot of wires, including copper and silver. Basically, use the largest copper that you can get (cheap one is ok), will provide significant result as long you use “enough” AWG. Off course, higher quality cable is better, but if you can’t get high quality enough, just make sure you get enough AWG size for applicable current.
We are not talking about technically required, but sonically enjoyed. Cheap industrial caps with enough capacitance and a little bit more than everage ESR is enough to smooth the power. But sonically enjoyed? I don’t think so. For example, I have Nippon Chemicon RWE on my other post. It’s high ripple current capacitor, low ESR, technically perfect as PSU caps. The sound? I don’t like it. I would prefer my ASC.
And one more things, with 60 Black Gate (30 in parallel each channel), I think the ESR would be lower than any available single caps solution on the market.
Thanks.

January 15, 2012 02:48It’s beautiful, Jimmy. I wonder how the sound would compare to the equivalent capacitance implemented using the screw terminal FKs.

January 15, 2012 13:00Hi Ben,
More capacitors usually better as they will have lower ESR than a single capacitor.
Thanks.
