History

Before 1989, TESLA was the main Czechoslovak producer of electron tubes. While TESLA vacuum tubes were exported all over the world, and were known for their quality, the company did not survive the change of economic system after 1989 in combination with the downturn in the vacuum tube market. JJ Electronic was founded in 1993, using the old TESLA machines for the manufacture of vacuum tubes. Eventually, JJ Electronic started to produce their own line of vacuum tubes and electrolytic capacitors, being mainly targeted at high-end audiophile and guitar amplifier applications.
