JJ Electronic

Formed in 1994 with former TESLA equipment, Jan Jorgo started JJ manufacturing with just three tube types - EL84, EL34 and ECC83. From these humble beginnings, JJ presently manufacturers close to 30 different tube as well as capacitors and amplifiers in a state-of-the-art facility in the picturesque Western Carpathian mountains of the Slovak Republic. JJ Tubes deliver solid performance with consistent quality and rich harmonic response. JJ tubes are the choice for amp manufacturers and listeners looking for quality European pedigree and tonality.
