Aerospace tubes, handbuilt sound
TENSA is a vacuum tube DJ mixer, handbuilt in Valencia. At its heart are miniature Soviet vacuum tubes originally developed in the 1960s for aerospace — extremely reliable, with an enormous
lifespan. Here they don't embellish the sound; they deliver absolute transparency and purity — living sound with no distortion or compression.
Every mixer is assembled by hand, pairing reference-grade sound with a design unlike anything else out there. The first limited series is now in production, and pre-orders are open — configure yours below or see the latest production update.
Built different.Sounds different.Feels different.
Soviet Aerospace Tubes
Rare Soviet dual-triode tubes, engineered in the 1960s for aerospace applications. Their unique characteristics allow operation at zero bias with high gain — letting us build the phono preamp from a minimal parts count for outstanding reliability and a clean, natural sound.
Iconic Form, Intuitive Flow
A truly original, seamless form finished with flanks of exotic hardwood. The layout is so classic and intuitive that anyone starts mixing right away — no manual needed.
Pure Linear Power Supply
Tubes demand flawless, noise-free power — so the supply lives in its own fully shielded external unit. A custom toroidal transformer with full galvanic isolation delivers 100+ dB SNR and zero dynamic compression.
Hybrid LED + Analog Metering
True stereo LED meters on every channel — Channel A, Channel B and Master — something almost no other mixer offers, paired with a pair of high-grade analog VU needles for precise, at-a-glance levels.
One Button, Full System
A single press powers the mixer and both turntables simultaneously — the PSU's switched outlets eliminate the ritual of waking up each device one by one.
More Mixer, Less Money
€1,990 (ex. VAT) — remarkable value for what it is. A send/return loop, balance control and three independent outputs (including a balanced booth feed), all around a tube signal path on space-grade tubes. No other boutique mixer comes close — at any price.
Latest Updates
Two mixers built, three more on the way
Two of our five pre-series mixers are built, three more are on the bench. Plus a night in Barcelona, better Alps faders, a steel enclosure and a configurator on the site.
The first unit is built
The plan was to build the first two TENSA units — and the first one is done: assembled, working, standing on olive wood cheeks. Here is what we had to fix, what we will improve next — and pre-orders are now open.
The PCB is final, the enclosures fit
The project has moved forward noticeably: the main mixer PCB is essentially finished and goes to production within the week, and the enclosures are already here — with everything fitting inside. In parallel: the wood, the packaging, and a dust cover of our own.
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 went to Superbooth in Berlin
In May we went to Berlin for Superbooth 26 — all three days of it. We didn't manage to set up our own booth this time, but we met great people and are already thinking about coming back next year with a spot of our own.
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.
Reserve your TENSA
Hand-built in small batches in Valencia. Choose the finish and the knobs, leave your contacts and we will get back to you with the details of the current batch.
The first batch is already in assembly. Demand has been overwhelming — thank you! We have doubled the batch, so preorders stay open. Every TENSA from this batch ships by the end of January 2027 at the latest.
