Trust your Tubes

TUBE-TECH Mission:


"It is our mission to ensure

the engineer has confidence

in his working tools and feels

comfortable working with them.

To achieve this, it is our job

to bring out the very best

in the tubes, as well as

continuously strive to offer

the professional

audio engineer

outboard equipment

of sublime quality–

both in terms of sound

and reliability."

Design Manifesto

Design Manifesto


The Five Axioms:


  • We shall only allow tubes to be used in the audio path
  • We shall optimise the performance of each tube
  • We shall aim for simplicity in circuitry and controls
  • We shall use transformers for all inputs and outputs
  • We shall design everything to last!



A Statement from the designer:


"Simply put, tubes sound pleasant to the ear. They treat signals with respect.
But perhaps more profoundly they place serious constraints on how much circuitry you can build into a unit.
With solid-state design, an engineer is free to ad circuitry with very little penalty, which can start you down the road of "fixing" percieved faults in the design with even more circuitry.
Unfortunately, the end result is usualy something that sounds worse than if the original circuit had been improved from the start.
As a result, I have to design very simple circuits.
There's no "patch" I can use to fix a circuit's faults. It has to stand by itself."
