One of must have software when simulating power supply is PSU Designer II or PSUD II. This amazing freeware could simulate your power supply behavior, before you start to assembly your circuit. Off course, not all looked good means good...

When it comes to high current and high efficiency, actually we don’t have much option rather than using switching based power supply. For most of consumer electronic equipment, this kind of power supply probably one of the best choice. But...

Today, I design the power supply module for my tiny amplifier project (check here and here for detail). The power supply are divided into three modules. One is for the 4x TBA820 (I stack 2 bridge diode to provide 3A...

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...

Finally, with the help from my girlfriend, I manage to get the Nuvotem Talema Transformer on hand within a week. It’s rated at 6.3A with 2x18V output or about 225VA. Not bad for my LM1875 huh…...

Still remember my other “stupidity” here? After several hours of investigation, I finally decide that the Jensen Copper Foil Paper Tube is not a good capacitor for bypassing purpose. The music will lose most of its detail. YMMV, this is...

I do love the improvement after I finish the VCap TFTF Capacitor Mods on my Aikido Power Supply. The staging is awesome. I could “see” not only a center point, but also a little bit left/right, even more left/right, left/right...

It’s a weekend holiday and it’s time to scratch my laziness and doing some audio DIY mods. This time, I will try a capacitor from Jensen, the 4-Pole Electrolytic. What makes it different from standard electrolytic? Well, it has 4...

If before I picked Obbligato as last Power Supply (High Voltage) bypass capacitor, now I’m experimenting with Jensen Pure Copper Foil Paper Tube in this position. The result? Well, not as significant as VCap on the first capacitor (after first...
