Special grid plated by gold to reduce microphone interaction and noise.
Once again a world class tube. Wonderful in Hi-Fi and guitar amps. Very smooth and detailed with a great open sound.

NOTE: The stock available at the moment comes from an exceptionally good production run, with noise and microphonic levels at the lowest rate possible. We invite you to stock them until available.

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.

      Buongiorno, no, queste sono delle ECC82, mentre la valvola equivalente della 6922 è la E88CC, suggeriamo una coppia di JJ serie Gold: https://www.playstereo.com/...
