Yamamoto A08-S Amplifier with Emission Labs tubes

We are changing to this new website design - It was necessary after using the old website since 18 years. All pages will be renewed in the coming months. Right now, many pages are still the old.


This is the official home page ofEmission Labs ®. We produce Directly Heated Tubes tubes, in our own factory in the Czech Republic,since 2001. Today, we depend on no other company for our production, meaning we have virtually any process in house. This ranges from glazing our own tube bases, to producing our own cathode wire and emission chemicals. The sound quality, lifetime and reliability our products is best reflected by the exceptional long warranty period we give now since 2013.
