The tubes we use in our microphones have been selected to give our customers the best performance possible with our designs. Low noise, sound quality and of course long life are taken into consideration with every design and subsequent tube selection.
The tubes are purchased in bulk from various manufacturers which we then subject every tube to a series of tests that start with a 'burn in' period that will result in those tubes that do not meet our high tolerances being rejected. We test for noise, microphonics and output.
These tubes have a very long working life and in many cases we have found RØDE tube microphones that have been used for over 10 years that still meet full specifications.
