E34LCZ/4 TAD selected power tubes, quartet (RT154)

The E34L is a long-life EL34 type tube with thick and especially solid glass. It delivers lots of bite in the top end, punchy mids and well-focussed bass power. A wonderful EL34, with great tone for Hi-Fi as well as for musical instrument amplifications.

Our burn-in process increases the electrical stability of this tube immensely. This increased stability is the basis for our subsequent matching process. Our TAD matching-process takes into account the dynamic aspects of tubes and allows for precise matching under real operating conditions. This process enables us to achieve an unparalleled sound quality.
