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

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?

I will continue my journey assembling the Mini Regulator. Now it’s the time for easiest part, the resistors and capacitors. To be honest, it’s not that easy - I mean, not as easy as I thought before

After around 1hour, I finish my job. Ta daaa… as below

I start to learn that DIY is not a matter of good sound, but also “eye catching” appearance. Well, I start it now. I “polish” the heatsink so it shines a little bit (rather than “dull” appearance). Then, I continue with picking colorful components. To be honest, it’s a little bit overkill to use Black Gate NX Series in this application. But I love the color combination and I believe you to. So? Just put it all down there.

The components are combination between Black Gate FK, Black Gate K, Black Gate NX, Black Gate N, and some resistors from Kiwame on most parts and one red one from PRP. Those Kiwames are carbon film, while PRP should be metal film. I pick PRP (despite of its red color) because this position is to set the maximum current of this regulator. Since PRP should be the regeneration of Holco, the most famous precision metal film resistor, so I do really can count on him. Oh, I also use old “dull color” green LED. This “dull color” LED should produce less noise than the newer “bright” LED.

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.

As I’ve promised before, my Gainclone project will be supplied with special smoothing capacitors. Welcome, the Black Gate F Series 680uF/65V. Each rail (positive and negative) will have 30 pcs of Black Gate capacitor, with total around 20.000uF capacitance each rail.

The main rectifier will be MUR860 and I will also use Snubber circuit, with the help of Mills and perhaps some oil capacitor. Hope it will sound good…

I’m thinking of… a full Black Gate Power Supply

Well, it’s not a dream since I have enough Black Gate F Series stock on hand. One value only, 680uF/65V. I need to use at least 10 pcs each (symmetrical power supply, remember? We are not talking tube, this is chip-amp project!). So total is at least 20 pcs. The troops are ready!
