colotube tube amplifier 300 B monoblocs

Imagine: You come home from a stressful day, sit down and start your colotube vacuum amplifier. Let the stress go and experience listening to music as being in a concert. The auditory spaciousness is going to take your breath. Never again do you want to miss your colotube amp.

Colotube vacuum tube amplifiers are 300 B triodes monoblocs with a sinus power output of 9 watt. They are the result of many years of R&D. Both devices are built mirror-inverted – for the most sophisticated demands on design. Each amplifier is hand-wired and hand-assembled in our family business. Handmade - in its purest form. Only components of the highest possible standards have been used, to optimize acoustic performance. Most obvious is the lasing 3 mm stainless chromium steel cabinet and its side parts in heartwood Wenge. The Pole Terminals and the RCA sockets are made by WBT, a German specialist. They are 24-carat multi-layer gold-plated and – as everything in and on a colotube – of highest quality. The tube sockets are made of Polytetrafluorethylon (likeTeflon), absorbing the vibrations coming from the transformer and the acoustic waves from the speakers. The Inox volume control with 26 positions has been improved by the Swiss jeweler Stefan Rüthy. Exclusivity and Design in the smallest detail.

All tubes are handmade today at Emission Labs in Prague. Built true to the original of the legendary Western 300B, but with the latest and highest quality material, each tube is numbered and has its test certificate. Pairs with similar test results are put together so that for both, the right and the left channel, we have similar conditions.
