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.
The JJ Tesla ECC802S is often used to replace the ECC82 12AU7 types. This valve has the long 17mm plate design used in the 1950s by Mullard with a longer fin to improve heat dissipation.

The ECC802S is an excellent sounding audio valve. It produces a rich warm sound which is both thick and fat. The valve is very musical and well balanced; it is easy to listen to with no harshness and it has plenty of detail in the upper mids with a fast smooth bass response. It has the classic Nos style warm audio sound.

We offer two options:
1) Factory tested from the JJ factory
2) Balanced -matched triode sections for Phase splitter, Audio & Tube microphones
