Thirty years ago, Penta Labs in California had a newly formed tube company JJ Electronics in Slovakia founded by Jan Jurco in 1993, produce a high end 12AX7. Using the Penta Labs t rademarked brand name Teslovak, they produced the E83CCS, a lower noise high end 12AX7. We have a few of these dated 1996. The new JJ factory was just 3 years old, time does fly when you're having fun. Show more
