A Brand New Innovation in the Valve industry! These are quite simply the best 12AX7 on the market and are guaranteed to improve your amp/valve pedal. We at GAK believe that the 12AX7T will very soon become the industry standard valve for all high-end amp manufacturers.

"For many years technicians have been working on a new 12AX7 following the principles of a revered engineer from the Brimar Standard telephone factory (UK) where I worked in the 1960's- this technician's name was Ernie Rowe.

Mr. Rowe's principle was not to over-engineer tubes by simply making them stronger or more rugged (WA versions), but instead he taught his team to follow good design principles, use only consistent fresh construction material, and to thoroughly educate and monitor staff performance. Rather than adopting accepted test procedures he designed application specific test procedures from which results were fed back to the design and production teams, for any
necessary procedural amendments.

Design considerations for trustworthy valves included the reduction of noise and elimination of rattle by 'locking the electrodes'. At Brimar these tubes were called "Trustworthy", and each tube was marked with a triangular trustworthy symbol. Now a new generation of 'Trustworthy' tubes is born that represents these same standards.
