Updates & Field Notes
This is where we document the build. Hardware decisions, sourcing updates, listening sessions, demo events — if something meaningful happens with TENSA, it lands here first.
We write for two kinds of readers: those who care about the technical side of what goes into a hand-built tube mixer, and those who just want to know where TENSA shows up next and what people think when they hear it.
The design is final — enclosures are off to production
We have finally locked the look of TENSA — so the first renders go straight into this update: the mixer and the power supply. The enclosures are heading to production, the silkscreen is final, and the workshop is filling up with components — top-shelf only.
TENSA at Ultrasound: DJs and Feedback
On May 13 we brought TENSA to Ultrasound, a vinyl shop in Ruzafa. Three hours: DJs behind the mixer, random shoppers behind the turntables, vintage VU meters on the table. The reaction was unanimous.
TENSA at Proyecto Juby: Jazz, Drum & Bass and House
On April 4, 2026, TENSA spent a full day at Proyecto Juby. Jazz, drum & bass, techno — and in the evening a vinyl set by @flacotrack through our tube mixer. Watch the video.
Podcast at Nekoza Records, Valencia
In March 2026, Evgenii Goriaev walked into Nekoza Records with the mixer and a microphone. An hour on why building a handcrafted tube DJ mixer still makes sense in 2026 — and what it sounds like.
The measurements match the ears
We measure TENSA constantly — noise floor, harmonics, channel crosstalk, and more. For this update: three key graphs with commentary.
TENSA — First Public Test. A Night at MAT32, Valencia
On February 20, 2026, the TENSA tube mixer left the workshop for the first time. A night at MA-32 vinyl bar in Ruzafa — three and a half hours of funk, house and disco, and one clear conclusion: everything works.
First Outing at Kultural Records Store
In mid-February 2026, the TENSA prototype ran on its own power supply for the first time — and around the same time left home for the first time. First stop: Kultural Records in Ruzafa.
The prototype came to life
February 3, 2026, my birthday — the TENSA prototype came to life for the first time. A steel sheet enclosure, cut, bent and painted by hand. Tube phonostages and all core functionality running. No wooden panels yet, but already a real mixer.
