I ordered custom made transformer to replace my old Aikido Pre-Amp transformer. Before, I rarely ordered a “finished” transformer (but prefer doing DIY one with my colleague). But now I’m thinking to try a “proven good” transformer (and considering doing...

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 😉...

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...

Never ending tweaks and mods? Yes I think so. Actually, my Aikido Pre-Amp already sounds good. But as a DIY, I think the journey never ends. Tomorrow always comes with another mods. After completing the PSU mods with Mundorf MCap...

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...

Still remember the extreme capacitors battle? Well, we need to break-in those capacitors first for a fair judgement. So here it is. I don’t have much time to break-in those capacitors. Around 2-3 hours/night for next 2-3 weeks. I think...

Just returned from a tired yet “deadly poisonous” DIY Gathering. We held an extra session with RGN 1054 Mesh Plate Rectifier and Duelund Capacitor installed on Aikido Pre-Amplifier (6N1P and 6N6P tubes). Before, the Aikido used Obbligato Capacitor bypassed with...

It was a nice session at DWA’s house located at Bintaro. We held a long session, from morning to night, from amplifier, preamp, DAC, to speaker. The event was started with a lunch 😉...

From my previous Aikido project, I’m still thinking of improvement of my B+ PSU. Well, I still hear a small hum. There are several possibilities to be tried, but I’m thinking of improving my B+ PSU first. If it fails,...

Finally, I put my Aikido Pre Amp on the chassis. Well, was a tough job since normally I didn’t do such thing (e.g. putting my DIY work on “little bit” neat chassis). I separated inside the chassis into 3 chambers....
