Elekit TU-8900 - 300B/2A3 SE Power Amp Kit

A Stunning Kit with Incredible Results

The Elekit TU‑8900 is one of those rare DIY kits where the finished product looks every bit like a high‑end commercial amplifier. Once assembled, it’s a genuinely handsome, beautifully finished piece of gear that would elevate the look of any hi‑fi system. It has real presence — the kind of amp you’re proud to display. From the moment the kit arrives, the experience feels premium. Everything is immaculately packaged, every component is accounted for, and the documentation is crystal clear. The PCB and parts quality are outstanding — easily among the best I’ve seen in a DIY kit. Building the TU‑8900 is a pleasure. The layout is logical, the instructions are easy to follow, and the whole process feels satisfying rather than stressful. My only advice: photocopy the manual prior to building, double‑check every component value and every solder joint. Do that, and the amp rewards you by powering up perfectly the first time. And the sound? Excellent. Clean, dynamic, and wonderfully musical — with the added bonus that you can tailor the character through tube rolling. Whether you prefer 300B or 2A3, the TU‑8900 lets you shape the sound to your taste. Highly recommended. If you want a top‑tier DIY amplifier that looks stunning, builds beautifully, and sounds fantastic, the TU‑8900 is an absolute winner.

A beautiful little amp.

I installed the TU8900 a few weeks ago and it’s been playing more or less continuously. Lovely sweet sound with surprisingly full and controlled bass. No regrets !
