Machines that once carried current now make sound. Yanko works with industry partners to rebuild retired power and electronic equipment into audio instruments with real HiFi performance. A background in industrial design and manufacturing, spent where materials, circuits, and acoustics meet.

Second lives, in sound.

Every piece carries a history worth listening to. Military-grade relays, transformers, capacitors — once built to be indestructible, retired decades later from the power grid.

I read its past and listen to its voice, then decide how it sings this time around.

HOW IT WORKS

Three things I always do.

Measure first

Every build hits the bench before I trust my ears — distortion, noise, response.

Keep the past

Relays, transformers, capacitors from the grid. Their history stays visible, not sanded off.

Sign it myself

Whoever measures it tunes it and signs it. That's the whole point, and the whole limit.
