The JJ factory was born out of the ashes of the former Tesla factory. They currently make a range of High quality valves based on some of Tesla most famous designs.
JJ 6SN7GT follows the American design of the 1950s but JJ have also made some excellent improvements to the 6SN7 which has resulted in a beautiful sounding audio valve.

JJ have used a thick glass envelope with a solidly constructed anode plate. These plates are supported with a metal claspes which are supported by connecting the top and bottom to the mica. This results in the valve being very resilient to microphonics and vibration.

JJ have also managed to produce an audio sound that rivals the best sounding vintage 6SN7 valves. It maintains a superb linear response and clear and musical sound characteristics.

Many customers have been thrilled with the performance of the JJ 6SN7 and at last we have found a superior sounding valve with ultra low noise at a sensible price
