Tesla started production in 1922 under its original name of Radioslavia Ltd in Czechoslovakia. It has a long history of manufacturing high quality transmitting valves and defense equipment. The Tesla factory was known for making some outstanding valves. The Original EL34 better in terms of microphonics and reliability than the famous Mullard EL34, hence Marshall used the Tesla EL34 from the mid 1970’s onwards. The frame grid E83CC was due to its construction the most expensive of it type to produce. Still to this day it is one of the best sounding ECC83/12AX7 types ever made. These are just a few of an endless list of pioneering valves produced by this great Czechoslovakian factory that sadly is no longer with us.
Original Tesla 6AQ5 EL90 with the 6L31 numbering in yellow print.
This small beam tetrode was used in the audio amplifiers of old home cinema equipment.It is also used as an output valve in high quality studio equipment.

Tesla used their own numbering 6L31 as these were supplied to the military and are tested for vibration and long life.

The Tesla are one of the best sounding 6AQ5 valves that I used in my Fender Musicmaster bass combo, which I used for guitar and bass

This item is an ideal choice in audio or guitar amplifiers and high end studio equipment
