This shop is specialized on production of JJ Electronic manufacturer.

In 1994, JJ Electronic started with the production of three types of tubes. Today, JJ electronic offers an assortment of more than 20 types of tubes. In 1999, capacitors and tube amplifiers were added to the JJ Electronic manufacturing program.
Every tube is electrically tested for all parameters which are the key to a flawless operation and a great sound. Specifically, these parameters include: leakage characteristics, internal vacuum level, cathode emission capability, filament voltage and current, anode current saturation level, microphony and others. Every month, random samples are taken from the production line in order to perform a life time test of 5000 hours under nominal conditions or 1000 hours at maximum specified ratings.
