It’s over midnight. After my previous mod on my Aikido Power Supply section here, it’s time to test it with RGN rectifier. I pick my Tefefunken RGN1054 Mesh Rectifier (before, I use Russian 5U4C, not a bad rectifier though). The...

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...

I dig my parts bin and found some resistor values which I needed to upgrade my Aikido. I used three brands here, Riken RMG “Metal Film”, Shinkoh “Tantalum”, and Kiwame “Carbon Film”. Lets fire up the soldering iron 😉...

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...

Yes, you might call me crazy! A Teflon VCap TFTF on Power Supply section? If I need to make myself clear, this 0.47uF/600VDC VCap TFTF Teflon capacitor will cost you around US$ 150 each (depends on quantity). So we will...

I just change my old “Aruki” Korean oil-can capacitor to ASC and Mundorf MCap Supreme. The configuration before is 60 uF and 40 uF Aruki Capacitor, now changed to 3.3 uF MCap Supreme and 40 uF ASC X386s. The effect?...

Just what I’ve promised before, finally today I do the most awaited Capacitors Battle. Actually the “real battle” will be done within next few days. Let’s say, this is as first impression to “hear” how good they would sound 😉...

Still remember my Aikido project? Until now, I’m still using Octal socket (since most of my rectifiers are Octal based, like 5U4, GZ37, etc).  Few weeks ago, I was poisoned with RGN Rectifier. Well, I knew this tube for long...

I have used this Vifa driver in my DIY loudspeaker for several years. Due to its pocket friendly price and also its performance. Yes, this is the cheapest Ring Radiator design (if you compare with the one from ScanSpeak). So...
