A warm welcome to Colotube

Colotube builds and sells High End vacuum tube amplifiers – in the UK valve amplifiers - at the highest quality standards. After years of research and development, we began to build triodes vacuum tube amplifier 300 B - monoblocs or Stereo. At the High End Munich Show we will present our new preamplifier.

We have united innovative techniques and stylish design which not only satisfy your ears. Each amplifier is numbered, hand-assembled and hand-wired in Lyss, Switzerland.
