Absolutely recommended! I purchased a Telefunken tube from Vacuum Tubus and I am extremely satisfied with the entire experience. The tube was exactly as described, in excellent technical and cosmetic condition, and most importantly, it sounds outstanding.
What I particularly appreciated was the professional and trustworthy service. The measurement values were provided to me immediately upon request, which gave me additional confidence in the purchase. When buying high-quality NOS tubes, transparency, reliable measurements, and careful selection are extremely important — and Vacuum Tubus delivered on all of these points.
Very friendly communication, fast and secure shipping, and above all, a truly excellent tube. I would not hesitate to buy from Vacuum Tubus again. Highly recommended!
Dear Dr. Nawartschi,

We look forward to assisting you again in the future.

Velocità nella spedizione e serietà con ottimi prodotti!
Well I couldn’t be happier with the store. When I was unsure till I had done some more research, they provided me with the info on how they had identified the valve cos it had lost its label and code. I verified and they are right. Good service so have used again. Valve is as described. Good bass extentin and smooth top. Sparkly but not too much. Running through tekefunken phase splitter and 1960 fat base Mullard rectifier. So, tight bass, warm and full with enough slam but not excessive. Lively fulll mid and detailed top. Not as clinical as an Amperex or telefunken, much more musical and cohesive. The instruments don’t stand in their own space, so if you want complete separation then it ain’t for you. Lovely straight wall of sound, which is what was looking for with this one. Glues the music together rather than letting you know exactly where everyone is. Sound stage is wide. I’m overall happy with it. Does what I wanted and sounds like it should.
