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. 

In addition we have a preamplifier in the same design.

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.

Come and enjoy listening to a colotube vacuum tube amplifier at no obligation.

We would enjoy hearing from you. Contact us today.
