Update on My AikiDino


After several weeks relying on the Solid State/Diode-based Rectification for B+ supply, which was a satisfactory experience, then with the great help from Pak Alex P of LJAudio (langsungjadi), I finally could enjoy the magical sound of Tube-based Rectification for My AikiDino!

The JAN 6x4 WA rectifier tube replaces the previous UF5407 bridged diodes.
And it truly leapfrogged my Aikido Preamp' performance to a higher level!!

What next? Hahahaha.. dunno yet... dunno yet...
I'm gonna just enjoy it sings beautifully, "working" hand-in-hand with my Monica3 Non OS DAC
(diyparadise.com), my Lucky13 LM3886 based power amp, my JBL E-30 speakers,
feed with audio signal from my good ol' NAD C521BEE cd player...

Beautiful glows.....

AikiDino Preamp

Some pictures of my first-ever experience in DIY Tube: AikiDino, a tube pre-amp inspired by the famous Mr. John Broskie's -wonderfully sounding- Aikido design! Thanks Mr. Broskie!

I used two pairs of 6N1P-EV Russian tubes, feed with approximately 170VDC as B+ supply from a solid state rectifier PSU unit
(plan to change to hybrid tube + solid state rectifier soon)


Initial setting with Bennic XPP as the output coupling caps




Quite messy layout eh? Crammed in a small space...

Lately, I changed the output coupling cap from Bennic XPP to a combination of Russian Paper-in-Oil caps K42Y-2 (green color) and Clarity Cap SA series (red color) as per picture below...


Expect sound improvement ? .... Of course!!
