Description

Quite possibly the most sturdy modern production triode we have seen, the JJ / Tesla 2A3 boasts up to 40 watts of plate dissipation. This 2A3 is single plate construction. The base is white ceramic with a glazed black face. This tube looks and sounds fantastic.

We now stock the new super-high quality JJ audio tubes. These tubes have consistently outperformed the competition in tone and sonic performance. Quality is the best we have seen from this factory.


JJ Overview
JJ Electronic was formed in 1993 out of the privatization of Tesla company. It is located in the heart of Europe, in the Slovak Republic. With over 25 years of experience in development and manufacturing of electron tubes, our staff is ready to meet the demands of today`s HI-FI and music instruments markets. JJ ELECTRONIC manufactures tubes on proven Tesla equipment modernized with the latest technology. 
JJ Testing
Every tube is electrically tested for parameters such as isolation characteristics, the electrode's current levels covering the entire operating curve, the condition of the vacuum, cathode emission capability, filament voltage and current levels. A microphonic test is performed on every tube. All tubes are then further burned-in for a period of 24 hours at the nominal specified operating voltage and current levels. Every month, a random sample is taken from the production to perform a life test of 5 000 hours at nominal operating conditions or 1000 hours at maximum specified levels.
