Description

JJ 12AX7S is considered to be one of the best for guitar and hifi applications. They simply sound better in most guitar amps than the other new 12AX7s. Most players prefer them for their warm sparkly sound.

Special grid plated by gold to reduce microphone interaction and noise.

This is the latest 12AX7 offering from JJ. The original JJ ECC83 was a great tube and came very, very close to my all time favorite Telefunken 12AX7’s. In fact it was very hard to tell them apart in some amps. The new "S" tube is even better! A tighter low end, a more natural and even more defined mid and the high end has more detail and is even sweeter than the original. The best part is that you can buy a new tube that sounds this good for one tenth the price of an NOS Telefunken.

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.
