New Tubes!


New tube types are in preparation for the upcoming High End show in Munich.


When we want to try new approaches in electron tubes we've always been restricted by the need to match the parameters of existing tube types. This time we did it differently. What if we give the new structure we want to try priority and see which parameters the resulting tube has? If it cannot match an existing type why not build the amplifier such that it fits?

If you look at some vintage tubes they sometimes have cylindrical arrangement of cathode, grid and plate. More modern tubes moved away from this structure. But sound wise the cylindrical arrangement was always superior when I compared tubes of the same type with round plates to those with box shaped electrode arrangement.

Initial trials in the tube factory came up with this tube which has a single filament string in the center, a cylindrical wound grid around it and all inside a cylindrical plate. This way the geometry inside the tube is always the same no matter in which direction you look from the filament to the plate.

Measurements confirmed the superiority of this arrangement with very linear plate curves which also reflects in the sound. Thus our new tube was born, the ONE.

The ONE can be used in the linestage our DAC output stage of the upcoming Intrepid product line.

It is exclusively made by Deutsche Elektronenröhren Manufaktur GmbH for use in my amplifiers and comes with a 5 year warranty.

The first production run of this tube is currently underway. But we won't stop here. We are working on two more tube types. One will be used as the driver tube in the Intrepid power amplifiers and the other will serve as output triode.

Here some pre production samples under test in the recently finished Heritage power amplifier. First series production is planned soon for these as well.

I am very excited to be able to offer these custom tubes as option in my upcoming amplifiers. I hope to have all three new types ready in time to show in Munich. Come to Hall 2, F06 to experience these.

Best regards



  1. Congratulation , the audio comunity really need a wide choice of new State of the Art tubes

  2. 843 Globes have this structure. A great tube ST or Globe. Thank you for introducing it to me.

    1. yes but the 843 is indirectly heated like many early indirectly heated triodes had such structure : 27, 56, 37, 76

    1. 316A? What makes you think that? No :-)

  4. This is super-exciting Thomas. A long-awaited new development.
