Burn-in Test & Matching of our Tubes !!!

Audiokit does  burn up/stabilization/measurement and matching of tubes before selling

We buy pentodes and dpower triodes alreay matched and tested (labeled also) by the fabric but we use to burn up them and do another test to verify the parameters and the stability. We do full burn up/measures/test and matching on double triodes instead, the tubes boxes (inside) are marked by us with a number to date back our measurement, you can request them by email
