Yamamoto A08-S Amplifier with Emission Labs tubes

EML45, burning in Yamamoto A08-S amplifier

We are changing to this new website design - It was necessary after using the old website since almost 20 years. All pages will be renewed in the coming months. Right now, a few pages are still the old.


This is the official home page of Emission 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 five years extended warranty, which program we have successfully started in 2013.
